Connected color workflow

v10.74 keeps the established color/conversion widgets intact while connecting picking, palette generation, contrast review, visual preview, scales and CSS/JSON reuse. Color work stays in the browser, and recent palettes can be stored locally without an account.

Color and accessibility boundaries

HEX/RGB/HSL/HSV/OKLCH conversions are numerical color-model operations. CMYK output is an RGB-derived approximation rather than ICC-profiled print proofing. WCAG contrast ratios measure luminance contrast only and do not certify a full interface. Color-blindness previews are design simulations, not medical tests.

How to use the Color Difference Calculator

Enter two HEX colors to convert each to D65 CIE L*a*b* and calculate their Euclidean ΔE*ab distance.

Method

This page uses the simple CIE76 formula. It is reproducible and useful for basic comparison, but newer ΔE formulas can model perceptual differences differently in demanding color-management workflows.
