FAQ
What is color contrast and why is it important?
Color contrast is the difference in brightness between a foreground color and its background. High contrast ensures that people with visual impairments can perceive your content effectively.
Are logos required to meet these standards?
No, the WCAG guidelines provide exceptions for text that is part of a logo or brand name, as well as text that is purely decorative or part of an inactive UI component.
How can I fix a low contrast ratio?
Increase the difference in luminance. Make the light color lighter or the dark color darker. Use our live preview to experiment.
