Convert CMYK to HSV
Converting Cyan, Magenta, Yellow, Key (black) (CMYK) 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 CMYK → HSV method, a worked example, a quick-reference table and the details that matter (rounding, gamut and print caveats).

How to convert CMYK to HSV
Take this real example — the color firebrick(#c2410c):
cmyk(0%, 66.49%, 93.81%, 23.92%) → hsv(17.47, 93.81%, 76.08%)
- Convert the CMYK color to RGB using the CMYK → 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.
CMYK → RGB → HSV (RGB is the numeric bridge)

About these formats
CMYK (Cyan, Magenta, Yellow, Key (black)). CMYK is the subtractive model of print: inks layered on white paper. On-screen CMYK values are approximations — real print depends on ink profiles (ICC), not just numbers.
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 CMYK to HSV?
Convert the CMYK color to RGB using the CMYK → 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 CMYK?
CMYK — Cyan, Magenta, Yellow, Key (black) — is the subtractive model of print: inks layered on white paper. On-screen CMYK values are approximations — real print depends on ink profiles (ICC), not just numbers.
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 CMYK → HSV conversion exact?
Yes. The formulas are deterministic and both formats store the same information for on-screen color; values are rounded only for display.
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.
