Accessibility and Design Quality Built In
Every extracted color is automatically checked against WCAG 2.1 accessibility standards. You see a contrast ratio and an AA / AAA / Fail badge for each hue — so you know immediately whether it meets web accessibility requirements.
ColorSense also includes Palette Health Score, which rates any palette across five dimensions: contrast, harmony, balance, vibrancy, and completeness. An AI model then suggests specific improvements.
