Brand Design tips
Many trendy brand colors (light tints, pastels) fail AA on white. Use the checker to find compliant combos before printing style guides.
For brand colors that need to work on both light and dark mode, test the same hex against #ffffff and #0f172a separately.
For CTAs, use the highest-contrast pairing — buttons need to read at a glance. Lower contrast is fine for less critical UI elements.
Document your AA-passing brand color combos in your design system so designers don't accidentally use failing combinations.
