FAQ

Why is gradient contrast harder?
Unlike solid backgrounds, gradients vary in brightness. Text readable on one part may be invisible on another. Test against the lightest and darkest stops of your gradient.
How do I pick gradient stop colors?
Sample the lightest and darkest points. If text passes WCAG AA against both extremes, it will be readable across the entire gradient.
