This page has no server side at all. The table you paste is parsed by JavaScript inside your own browser, the chart is drawn on a canvas element on your machine, and the export file is assembled locally. Nothing is uploaded, stored or written to any log. You can disconnect from the network after the page has loaded and everything will still work — which is the simplest way to verify the claim yourself.
Facts and limits of this method
| Intermediate step | HSV is first converted to RGB, then to HEX |
|---|---|
| Hue range | 0° to 360° (out-of-range values are wrapped with modulo) |
| Saturation and value range | 0% to 100% |
| Result format | #RRGGBB — six hexadecimal digits |
When it misleads you
- Hue 360° and hue 0° both correspond to the same color (pure red) — the converter automatically wraps hue values modulo 360.
- At zero saturation, hue has no effect on the result — you get a shade of gray determined only by value.
- The result is standard 6-digit HEX; rounding of fractional intermediate calculations may cause a ±1 RGB deviation compared to another calculator's output.
- Like any HEX code, the result carries no information about a specific screen's color profile.
How it is calculated
Saturation and value are converted to fractions from 0 to 1 by dividing by 100.
Chroma C = V × S, an intermediate value X, and the offset m = V − C are computed using the standard HSV formulas.
Depending on which of six 60° sectors the hue H falls into, the (R', G', B') values are picked from C, X and 0, m is added, the result is multiplied by 255 and rounded.
The resulting R, G, B are converted to two-digit hexadecimal pairs and joined into a 6-digit HEX code with a leading "#".
Questions and answers
What happens if I enter a hue above 360° or negative?
The converter automatically wraps hue into the 0°–360° range using modulo, so the result is always valid.
Why is the result gray regardless of hue when S=0%?
At zero saturation the color becomes achromatic (a shade of gray), and hue has no visual effect in that case.
Can I get a pure white or black HEX code?
Yes: V=100% with S=0% gives #FFFFFF (white), and V=0% (regardless of S and H) gives #000000 (black).
Is my data sent anywhere?
No, the whole calculation runs in your browser.
