Colors and Fonts in a Presentation — How to Choose the Perfect Combination

Imagine opening a presentation you spent many hours working on. The content is solid, the data is reliable, the arguments are well thought out. And yet something is off — the slides look unprofessional, the text blends into the background, and the whole thing resembles a school project rather than serious material. The cause is almost always poorly chosen colors and fonts in a presentation.

This is a problem most people creating presentations struggle with. Without basic knowledge of typography and color theory, even the best content loses its impact. Carelessly chosen fonts suggest a lack of professionalism, and garish colors distract attention from the substance. Instead of focusing on data and conclusions, the viewer fights with unreadable text or is distracted by visual chaos.

In this article, I will show you specific rules that will allow you to consciously choose colors and fonts for any type of presentation. You will find ready-made color palettes with hex codes, proven font combinations, and practical tools that simplify the entire process. Whether you are preparing a corporate presentation, a pitch deck, or material for university — these principles will work.

Why colors and fonts matter

Research in the psychology of perception clearly indicates that people form an opinion about visual content within the first 90 seconds of contact — and up to 90% of that assessment is based on colors. This means that before the viewer reads the first bullet point on a slide, their brain has already decided whether the presentation looks professional or amateurish.

Colors work on an emotional and subconscious level. Blue builds trust and is associated with competence — it is no coincidence that most financial corporations use shades of navy and sky blue. Red signals urgency and energy, but in excess it creates tension. Green calms and evokes associations with nature, balance, and growth. Yellow attracts attention, but too intense a shade tires the eyes. Conscious color selection allows you to steer the viewer's mood and reinforce the message.

Typography plays an equally important role. A font is not just a text carrier — it is a visual element that communicates the character of the presentation. A serif font lends a formal, academic tone. A sans-serif font is associated with modernity and cleanliness. A decorative handwritten font can look creative on one slide, but becomes unreadable when the entire presentation is based on it. Well-chosen colors and fonts in a presentation create a cohesive visual system that guides the viewer's eye and facilitates information absorption.

This is precisely why companies spend thousands on visual identity, and designers spend hours testing palettes and font pairings. It is not about aesthetics for its own sake — it is about communication effectiveness.

When color and font choices are crucial

While colors and fonts matter in every presentation, there are situations where their role becomes absolutely critical:

Corporate and branding presentations. When you create slides under a specific brand, you must stick to its visual identity. Using the wrong colors or fonts undermines brand consistency and looks unprofessional. The company's brand book defines permissible colors, fonts, spacing, and logo variants — it is your design bible.

Formal and academic presentations. A thesis defense, a scientific conference presentation, or a board meeting — these are situations where the appearance of slides builds (or undermines) your credibility. A subdued palette, readable typography, and high contrast are a requirement, not an option. The viewer must be able to focus on the content rather than decipher decorative fonts.

School and university presentations. Students often reach for bright colors and decorative fonts, thinking this will make the presentation more attractive. In practice, the effect is the opposite — the instructor perceives such slides as chaotic and poorly thought out. Even at university, it is worth applying professional design principles.

Pitch decks and sales presentations. When you are competing for an investor, client, or contract, colors and fonts in a presentation can determine the first impression. An investor sees dozens of pitch decks per week. The one that looks professional and cohesive automatically gains an advantage over the visual chaos of the competition.

How to choose colors and fonts step by step

Choosing colors and fonts does not have to be a process based on intuition. There are specific, repeatable methods that produce a professional result even without graphic design experience.

The color wheel and color harmonies

The color wheel is a designer's fundamental tool. It allows you to create color harmonies — sets of colors that naturally work well together:

• Analogous harmony — three colors adjacent on the color wheel (e.g., blue, blue-violet, violet). It produces a calm, cohesive effect. Ideal for corporate and scientific presentations.
• Complementary harmony — two colors opposite each other on the wheel (e.g., blue and orange). It creates strong contrast and dynamism. Works well in sales presentations where you want to draw attention to key elements.
• Triadic harmony — three colors evenly spaced on the wheel (e.g., red, yellow, blue). Vivid and balanced, but requires careful dosing.
• Monochromatic harmony — different shades and saturations of a single color. The safest option, minimizing the risk of a color faux pas.

Practical tip: start with one primary color that fits the topic and context of the presentation, then use the color wheel to select the remaining 2-3 colors in your chosen harmony.

Contrast and readability

Contrast is the most important aspect of color selection in a presentation. The most beautiful palette is worthless if the text is unreadable against the background. The WCAG AA standard requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large headings.

A few practical rules:

• On a light background (white, light gray, cream), use dark text — dark gray (#1F2937) or dark navy (#1B2A4A), not pure black (#000000), which is too harsh.
• On a dark background (navy, dark gray), use light text — white (#FFFFFF) or light gray (#F1F5F9).
• Avoid text on photos without darkening or lightening the background — a semi-transparent overlay solves this problem.
• Never combine two saturated colors (e.g., red text on a blue background) — they create a "vibrating" effect that is extremely tiring for the eyes.
• Test contrast on a projector — projectors "wash out" colors, so the contrast should be higher than on a monitor.

Font pairing

The golden rule of presentation typography is: use a maximum of two fonts — one for headings, one for body text. A well-chosen font pair should create contrast (so the heading stands out from the text) while maintaining harmony (so the whole thing looks cohesive).

Proven pairing methods:

• Serif + sans-serif — a classic combination: a serif font for headings gives them character, while a sans-serif for text ensures readability.
• Two sans-serifs with different characters — a geometric font for headings (e.g., Poppins, Montserrat) and a humanist one for text (e.g., Inter, Open Sans).
• Fonts from the same family — e.g., DM Serif Display + DM Sans. They guarantee a perfect match in proportions.

Avoid combining two fonts with too similar a character (e.g., Arial and Helvetica) — the difference will be invisible and unnecessary. Also avoid combining two decorative fonts — the result will be overwhelming.

Tools for choosing colors and fonts

You do not have to rely solely on your own eye. There are many free tools that professionally support the selection process:

• Coolors.co — a color palette generator. Press the spacebar and the tool generates a harmonious 5-color palette. You can lock colors you like and generate new ones in their context.
• Adobe Color — an advanced color wheel with harmony rules (analogous, complementary, triadic). The "Extract from Image" feature automatically creates a palette from a photo.
• WebAIM Contrast Checker — enter the text and background colors, and the tool instantly shows whether they meet the WCAG AA/AAA standard.
• Google Fonts — over 1,500 free fonts with previews, filtering, and pairing suggestions in the "Pairings" tab.
• Fontjoy — a font pairing generator powered by machine learning. It generates harmonious combinations with a single click.
• Typescale — a typographic hierarchy calculator. Define the base size, and the tool generates a proportional scale for headings and text.

Most common color and font mistakes

Knowing the most common mistakes makes them easier to avoid. Here are the problems I see most often in presentations — from school to corporate:

Too many colors. This is by far the most common mistake. Every slide in a different color scheme, five different text colors, rainbow charts — the result is visual chaos. Limit yourself to 3-4 colors and use them consistently throughout the entire presentation. Consistency is more important than color creativity.

Decorative and ornamental fonts. Comic Sans, Papyrus, fonts imitating handwriting or gothic letters — these are the plague of amateur presentations. Decorative fonts can work in the title of a single slide, but on larger areas of text they become unreadable and unprofessional. Stick to proven sans-serif fonts for body text.

Too low contrast. Light gray text on a white background, yellow text on a light background, dark gray text on a black background — these are classic examples of low contrast that make a presentation unreadable. This is especially dangerous on projectors, which further "wash out" colors. Always verify contrast with a tool like WebAIM Contrast Checker.

Inconsistency between slides. The heading on one slide is blue and set in Montserrat, on the next it is green and in Arial, and on the third it is red and in Times New Roman. Such inconsistency signals a lack of planning and undermines professionalism. Establish a color and font scheme at the beginning and apply it to all slides without exception.

Ignoring the display context. Colors that look great on a Retina monitor may be completely unreadable on an old projector in a bright room. A dark background looks beautiful on a laptop screen, but on a projector in a room with windows the text will be invisible. Always consider the conditions under which the presentation will be displayed and adjust the colors and fonts in the presentation accordingly.

How AI automatically selects colors and fonts

Manually selecting colors and fonts requires knowledge of color theory, typography, and contrast principles. For people without graphic design experience, this is often the most difficult stage of creating a presentation. This is precisely why modern AI-powered tools are taking over this role.

AI presentation generators analyze the topic, context, and purpose of the presentation and then automatically select a harmonious color palette, professional fonts, and appropriate contrast proportions. The algorithms take into account the principles discussed above — the color wheel, color harmonies, WCAG readability standards, and proven font pairings.

As a result, the user does not need to know hex codes or remember which fonts pair well together. AI makes these decisions based on data about the effectiveness of various visual combinations, eliminating the most common mistakes: too many colors, low contrast, or typographic inconsistency. This is especially valuable when you need colors and fonts in a presentation chosen quickly and professionally, without hours of manual testing.

How to generate a presentation with consistent visual identity

Prezentacje AI is a tool that automatically generates complete presentations with professionally selected colors and typography. Simply describe the topic in the chat interface — AI will prepare slides with a cohesive color palette, appropriate fonts, proper contrast, and a readable typographic hierarchy.

If the generated palette does not meet your expectations, you can ask the AI to change the color scheme (e.g., "switch to a dark background with purple accents" or "use my company colors: navy and gold") and receive an updated version in seconds. You can also modify individual slides while maintaining the overall visual consistency of the entire presentation.

Generated presentations can be exported to PPTX format and further edited in PowerPoint or Google Slides, preserving all color and font settings. This is the way to achieve professional colors and fonts in a presentation without having to learn graphic design.

Frequently asked questions

How many colors should I use in a presentation?

The optimal number of colors in a presentation is 3-4: one dominant color (background or large surfaces), one accent color (headings, highlights, icons), one main text color, and optionally one additional color. More than 5 colors creates an impression of chaos and distracts attention from the content.

What are the best fonts for a presentation?

For body text in a presentation, readable sans-serif fonts work best, such as Inter, Open Sans, Lato, or Roboto. For headings, you can use more distinctive fonts, e.g., Montserrat, Poppins, or Playfair Display. The key is to limit yourself to a maximum of two fonts and maintain consistency across all slides.

How to choose colors for a corporate presentation?

In a corporate presentation, base your choices on the brand's visual identity colors. Use the main brand color as an accent (not as a background), add neutral shades of gray or white as a base, and supplement with one additional color from the brand book palette. Check that the text-to-background contrast ratio meets the minimum of 4.5:1.

Can I use a black background in a presentation?

Yes, a dark or black background in a presentation is acceptable and can look very impressive. It works especially well in dimmed rooms, on large screens, and in tech or premium presentations. Keep in mind, however, that a dark background is unreadable on projectors in bright rooms and requires light text colors with high contrast.

What font size should I use in a presentation?

The minimum font size in a presentation is 20 pt for body text, 28-36 pt for subheadings, and 36-44 pt for slide headings. Chart labels and footnotes can be 16-18 pt. The larger the room, the larger the font should be. A practical rule: divide the age of the oldest audience member by 2 to get the minimum size in points.

Summary

Choosing colors and fonts in a presentation is the skill that separates professional slides from amateurish ones. You do not need to be a graphic designer — a few proven rules are enough:

• Limit the palette to 3-4 colors — one dominant, one accent, one for text, and one neutral. More means chaos.
• Text-to-background contrast must meet a 4.5:1 ratio — test with the WebAIM Contrast Checker, do not rely on your eye alone.
• Use a maximum of 2 fonts — one for headings (can be serif), one for text (preferably sans-serif).
• Minimum text size is 20 pt — for large rooms, even 28-30 pt.
• Maintain consistency — the same colors and fonts on all slides, without exception.
• Adapt to the context — dark backgrounds on large screens, light backgrounds in bright rooms with projectors.
