What is the valid range for X, Y, and Z?

For the D65 sRGB reference white the normalized range is X=0–0.9505, Y=0–1.0000, Z=0–1.0890. Values outside this range are accepted; resulting RGB channels are clamped to 0–1 before HSV conversion and an out-of-gamut warning is shown.

What happens when an XYZ color is outside the sRGB gamut?

Many XYZ colors cannot be represented in sRGB. This tool clamps each linear RGB channel to 0–1 before gamma encoding, which produces the nearest displayable color. An out-of-gamut warning appears when clamping occurs.

Which illuminant does this tool use?

D65 (standard daylight, 6500 K) with reference white Xn=0.95047, Yn=1.00000, Zn=1.08883. D65 is the standard illuminant for sRGB and is the most common choice for web and display work.

How is HSV calculated from sRGB?

Value equals the maximum sRGB channel. Saturation is the difference between max and min channels divided by max (zero when max is zero). Hue is derived from which channel is dominant and the relative channel differences, producing a 0–360° angle.

What does X=0.4124, Y=0.2126, Z=0.0193 convert to in HSV?

Those XYZ values correspond to sRGB red (#FF0000), which in HSV is hsv(0, 100%, 100%) — a fully saturated red at full brightness.

What is the difference between HSV and HSL?

Both share the same Hue axis. In HSV, Value measures brightness from black to the pure full color. In HSL, Lightness goes from black through the pure color to white. A fully saturated pure color has V=100% in HSV but L=50% in HSL.

Does this tool send any data to a server?

Summary

Enter CIE XYZ tristimulus values and instantly get the equivalent HSV color with hue, saturation, and value outputs plus a live preview swatch.

How it works

Enter X, Y, and Z values using the number inputs or sliders (typical normalized range 0–1; D65 reference white is X=0.9505, Y=1.0000, Z=1.0890).
XYZ values are multiplied by the inverse sRGB D65 matrix to produce linear RGB channel values.
Linear RGB is gamma-encoded with the sRGB transfer function (IEC 61966-2-1) to produce non-linear sRGB in the 0–1 range.
sRGB values are clamped to 0–1 (out-of-gamut XYZ inputs are flagged) and converted to HSV via the standard max-min algorithm.
Hue (0–360°), saturation (0–100%), and value (0–100%) are displayed alongside the hsv() string.
A live color swatch previews the resulting color; copy buttons let you grab the hsv() string instantly.

Use cases
