How to Choose a Color Palette for Presentations
Slides have a problem websites don’t: projectors wash out color and the room may be bright. A presentation palette has to be readable from the back row. Here’s a simple system that survives the real world.
- You need just three roles: a slide background, a text color, and one accent
- Projectors flatten contrast, so push it further than feels necessary — dark background with light text often projects best in bright rooms
- For charts, use a small set of clearly distinct colors and label directly
Keep It to Three Roles
A deck doesn’t need a rich palette — it needs clarity. Define a background, a text color with strong contrast against it, and one accent for emphasis and key data. Use the accent sparingly so it actually draws the eye to what matters.
Push Contrast Harder Than You Think
Projectors lower contrast and ambient light washes slides out, so a pairing that looks fine on your monitor can be unreadable in the room. Aim well past the minimum — high contrast between text and background is the single most important factor for legibility from the back row.
Dark or Light Background?
Both work, but consider the room. In bright rooms, a dark background with light text often projects with punchier contrast and less glare. In controlled, dim rooms, light backgrounds look clean and modern. When unsure, dark-on-light text at high contrast is the safe default.
Colors for Charts and Data
Data slides are where palettes fall apart. Limit chart series to a few clearly distinct colors (your accent plus two or three supporting hues), and label series directly instead of relying on a tiny legend. Avoid red/green as the only distinction — it fails for colorblind viewers and on bad projectors.
Frequently asked questions
How many colors should a presentation use?
Three is plenty: a background, a high-contrast text color, and one accent for emphasis and key data. Extra colors usually hurt clarity rather than help.
Should presentation slides have a dark or light background?
Both can work — match the room. Dark backgrounds with light text often project better in bright rooms; light backgrounds look clean in dim, controlled spaces. Prioritize high contrast either way.
What colors should I use for charts in a deck?
A few clearly distinct colors — your accent plus two or three supporting hues — and label each series directly. Avoid relying on red/green alone, which fails for colorblind viewers and weak projectors.
