FAQ

Still have questions?

What is the RGB equivalent of a LAB color?

CIE L*a*b* is first converted to CIE XYZ using the D65 reference white, then XYZ is converted to linear RGB using the inverse sRGB matrix, and finally gamma-encoded back to standard sRGB. L* is lightness from 0 (black) to 100 (white), a* runs from green (negative) to red (positive), and b* runs from blue (negative) to yellow (positive). For example, lab(43, 65, -79) is roughly RGB(124, 58, 237). This tool does the math automatically.

How do I input LAB values into this converter?

Enter your LAB values in any common format: lab(43,65,-79), 43, 65, -79, or 43 65 -79. L accepts 0-100, a and b accept -128 to 127, and the tool is forgiving with spacing and punctuation. You can also use the color picker.

Does this tool store or upload my colors?

No. Every conversion happens locally in your browser. Nothing you type or pick is sent to a server.

Can I convert RGB back to LAB?

Yes - use the RGB to LAB converter for the reverse direction, or any of the other format converters linked below.

Why might a LAB color not have an exact RGB match?

LAB covers a wider range of colors than a screen using sRGB can display. If a LAB value falls outside the sRGB gamut, the converted RGB channels are clamped to the nearest displayable value (0-255), so the result you see is the closest reproducible approximation rather than a perfect match.

Is there a limit on how many colors I can convert?

No. Convert as many colors as you like, for free, with no account required.
