Level: Intermediate
An accessible palette accounts for color blindness and low-vision needs from the start, rather than retrofitting fixes after the fact.
Never Rely on Color Alone to Convey Information
Any information communicated through color — an error state, a status indicator — should also be communicated through text, icon, or pattern for visitors who can't distinguish the color difference.
Check Your Palette Against Common Color Blindness Types
Simulating how your palette appears under different types of color vision deficiency reveals combinations that might be indistinguishable to a meaningful share of visitors.
Maintain Sufficient Contrast Across Every Combination You Actually Use
Every text-and-background pairing that appears anywhere on the site should be checked individually, not just your primary combination.
Next step: Use the Color Picker to verify every color combination in your palette meets accessible contrast standards, not just your primary text and background pairing.
