CMYK to HSV Converter

Conversion procedure

1. Parse CMYK: accept cmyk(c%, m%, y%, k%) or four comma-separated numbers. Each of C, M, Y, K is expected in 0–100, representing ink percentages for the simple subtractive model used on this site (not a specific printer ICC profile).
2. Convert CMYK → sRGB: using normalized c,m,y,k ∈ [0,1], the tool applies the standard inverse: R = 255 × (1 − c)(1 − k), G = 255 × (1 − m)(1 − k), B = 255 × (1 − y)(1 − k). Integer CMYK can match more than one RGB after rounding; when several triples yield the same rounded CMYK, this site picks the one aligned with the Color Picker’s convention so copied CMYK values round-trip to the same HEX shown there.
3. Build HSV: V = max(R,G,B) (as a 0–100% value after scaling), S = 0 if V = 0, else S = (max − min) / max × 100. Hue uses the same 60° family of cases as the HSL step. Output is integer hue and whole percentages: hsv(h, s%, v%).
4. Finalize: the result string is what you copy from the calculator. The line under the fields summarizes the path in short form (HSV ← sRGB ← CMYK). Rounding is intentional so values read like typical CSS; tiny differences versus other apps can still appear because of integer hue, saturation, lightness/value, or ink percentages.
5. CMYK reminder: this model is a screen-side approximation. For print-critical work, follow your printer or PDF export profile; use HEX/RGB on this site as the authoritative on-screen reference. HSL/HSV reminder: when hue, saturation, and lightness/value are shown as whole numbers, more than one underlying RGB can produce the same text. Typing those integers back into a converter may therefore differ by ±1 from a color you first picked as HEX in the Color Picker—that is expected rounding behavior, not a broken formula.
