Convert HEX to HSV
Converting hexadecimal (HEX) to Hue, Saturation, Value (HSV) is a precise, rule-based operation — both formats describe the same color with different numbers. Whether you are tuning a CSS custom property, matching a brand color across design tools, or preparing values for print, this page gives you an interactive converter, the exact HEX → HSV method, a worked example, a quick-reference table and the details that matter (rounding, gamut and print caveats).

How to convert HEX to HSV
Take this real example — the color firebrick(#c2410c):
#c2410c → hsv(17.47, 93.81%, 76.08%)
- Convert the HEX color to RGB using the HEX → RGB method.
- Keep the three RGB channels (0–255) — this is the shared numeric base of every on-screen format.
- Convert RGB to HSV with the RGB → HSV method to finish.
HEX → RGB → HSV (RGB is the numeric bridge)

About these formats
HEX (hexadecimal). HEX is the web's native notation: a # followed by two digits per channel in base 16 (00–FF). Compact, unambiguous and supported everywhere, from CSS to design tools.
HSV (Hue, Saturation, Value). HSV is like HSL but with brightness ("value") instead of lightness — the model behind classic color pickers and graphics software (also called HSB). An industry convention, not a CSS space.
Frequently asked questions
How do I convert HEX to HSV?
Convert the HEX color to RGB using the HEX → RGB method. Keep the three RGB channels (0–255) — this is the shared numeric base of every on-screen format. Convert RGB to HSV with the RGB → HSV method to finish. The converter above does it instantly, including the reverse direction.
What is HEX?
HEX — hexadecimal — is the web's native notation: a # followed by two digits per channel in base 16 (00–FF). Compact, unambiguous and supported everywhere, from CSS to design tools.
What is HSV used for?
HSV (Hue, Saturation, Value) is like HSL but with brightness ("value") instead of lightness — the model behind classic color pickers and graphics software (also called HSB). An industry convention, not a CSS space.
Is the HEX → HSV conversion exact?
Yes. HEX and RGB encode the identical numbers in different notations, so the conversion is exact in both directions with no rounding.
Why does the HSV value look different in other tools?
Small differences come from rounding (how many decimals are kept) and from out-of-gamut handling. This site follows the CSS Color 4 algorithms and shows OKLCH with 3 decimals, the same convention used by browsers and mainstream design tools.
