Convert CIELAB values to HEX codes with live, two-way sliders.
LAB values turn up wherever color gets measured: spectrophotometer readouts, brand-color specifications, print proofs, Photoshop's Lab mode, and modern CSS lab(). To use one of those colors on the web you usually need a HEX code, and that's exactly what this tool produces. Set L (0–100), a (green–red) and b (blue–yellow), and read the #RRGGBB — plus RGB, HSL, LCH, OKLCH, HWB and CMYK — instantly.
The conversion uses the D50 white point, the same convention as CSS, ICC profiles and Photoshop, so numbers you carry over from those tools land on the same color here. LAB is much bigger than the sRGB gamut, so extreme values are clipped to the closest color a screen can actually display.
Going the other way? Use the HEX to LAB converter, work in polar form with LCH to HEX, or browse all our free color tools.
Set L (0-100), a and b (each -125 to 125) with the sliders or number boxes. The tool converts through the XYZ color space to sRGB and shows the matching HEX code instantly.
Yes. Photoshop’s Lab mode and this converter both use the D50 white point, so the same L, a, b numbers produce the same color. Small last-digit differences can appear because Photoshop rounds its display values.
LAB can describe colors far outside what screens display, such as ultra-saturated yellows. When your values fall outside the sRGB gamut, the converter clips to the nearest displayable color, so several extreme inputs may map to the same HEX.
OKLCH, LCH and LAB can describe colors that no screen pixel can show. When a slider combination lands outside the sRGB range, the tool clips it to the nearest displayable color, so extreme chroma values may snap back once converted.
Completely. The conversion runs entirely in your browser with JavaScript, nothing you enter is uploaded or logged, and the page keeps working offline once loaded.
