Color contrast is about how easy it is to tell the difference between the color of text and the background behind it. Picture writing with a yellow marker on a white piece of paper—it’s really hard to see the letters. But if you use a black marker instead, the letters stand out much better. That’s because black and white have great color contrast.
Why does color contrast matter?
It helps everyone read easily
Good color contrast makes it easier for readers to see what’s written—especially people who might not see colors the same way or have difficulties with their vision.
It keeps readers comfortable
Poor contrast makes you work harder, and that can get tiring. With good contrast, reading feels smoother and more comfortable.
It’s like turning on a light
If the colors are too similar (like light gray text on a white background), it’s like trying to read in the dark. Strong contrast (like black text on white) is like flipping on a bright light—it’s so much clearer!
Steps to improve accessibility with color contrast
- Use strong contrast, like dark text on a light background or light text on a dark background. Black on white works well. Pale gray or yellow on white does not.
- Think about colorblindness: Some people can’t tell red from green or blue from yellow. Don’t use color combinations that could be difficult to tell apart.
- Test It: If you squint at the page, and the text disappears, your contrast is not good enough.
Picture this:
You’re on a TV streaming service and the program titles are white text over the program’s picture. You squint and try your best, but it’s hard to figure out what it says. That’s frustrating, right? Now imagine the same titles in bold black on white—it’s way easier to find what you want. That’s why color contrast matters—it helps everyone get the information they need.
