LAB Color Converter

Compare perceptual LAB coordinates with familiar HEX/RGB output using the standard sRGB D65 reference white.

—L*
—a*
—b*
—sRGB HEX
D65 sRGB / CIELABConversion uses the sRGB D65 reference white. LAB values outside the sRGB gamut are clipped when converted back for display.

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 LAB Color Converter

Convert a display sRGB color to CIE L*a*b*, or enter D65 LAB coordinates and view the nearest clipped sRGB display result.

Method and limit

The conversion uses the standard sRGB transfer curve, XYZ, and D65 reference white. LAB colors can exist outside the sRGB gamut, so reverse conversion may clip channel values for display.
