What XYZ range should I enter?

For D65-normalized sRGB, X ranges roughly 0–0.9505, Y ranges 0–1.0000, and Z ranges 0–1.0890. Values outside the sRGB gamut are clamped to the nearest displayable color.

Which white point does this tool use?

This tool uses the D65 illuminant (daylight 6500 K), the standard reference white for sRGB. Under D65, pure white is approximately X=0.9505, Y=1.0000, Z=1.0890, which maps to #FFFFFF.

What happens with out-of-gamut XYZ values?

XYZ values outside the sRGB gamut produce linear RGB channels below 0 or above 1. These are clamped to the 0–1 range before gamma encoding, giving the nearest displayable sRGB color.

What is the sRGB gamma encoding step?

After the matrix multiply, each linear channel is encoded with the sRGB transfer function: for values above 0.0031308, the formula is 1.055 * v^(1/2.4) - 0.055; for values at or below 0.0031308, it is 12.92 * v. This matches IEC 61966-2-1.

How is this the inverse of RGB to XYZ?

The forward conversion multiplies linearized RGB by the D65 sRGB-to-XYZ matrix. This tool applies the mathematical inverse of that matrix, then re-applies the sRGB gamma curve to recover the original hex code.

Does this tool send my data anywhere?

No. All conversion math runs entirely in your browser using JavaScript. No data is sent to any server.

Summary

Enter CIE XYZ tristimulus values and instantly get the sRGB hex color code with a live color swatch.

How it works

Enter X, Y, and Z values in the input fields (valid range roughly 0–1 for D65-normalized sRGB).
The tool multiplies the XYZ values by the inverse D65 sRGB matrix to obtain linear RGB.
Each linear channel is gamma-encoded using the IEC 61966-2-1 sRGB transfer function.
Linear values are clamped to 0–1 before encoding to stay within the sRGB gamut.
The resulting R, G, B values (0–255) are formatted as a 6-digit uppercase hex code.
A live color swatch and one-click copy button update instantly as you type.
