How to Convert CMYK to HEX

The conversion process involves parsing CMYK values and converting to hex format: Parse the cyan, magenta, yellow, and black ink values and transform them to hexadecimal color representation.

Conversion Process:

1. Parse CMYK → Normalize: Convert CMYK values to 0-1 range
2. CMYK → RGB: Calculate RGB values from ink percentages
3. RGB → HEX: Convert RGB to 6-digit hexadecimal
4. Format Output: “#” + hexString.toUpperCase()

Example (cmyk(0%, 100%, 100%, 0%)): C:0, M:1, Y:1, K:0 → #FF0000

Example (cmyk(100%, 0%, 100%, 0%)): C:1, M:0, Y:1, K:0 → #00FF00

Example (cmyk(100%, 100%, 0%, 0%)): C:1, M:1, Y:0, K:0 → #0000FF

Step-by-Step Conversion Process:

  1. Validate Format: Ensure CMYK values are in correct format
  2. Parse Components: Extract C, M, Y, K values from cmyk() or comma-separated format
  3. Normalize Values: Convert percentages to 0-1 range for calculations
  4. Calculate RGB: Use CMYK to RGB conversion formulas
  5. Convert to Hex: Transform RGB to 6-digit hexadecimal
  6. Format Output: Add # prefix and ensure uppercase

Understanding CMYK Components:

Cyan (C): Blue-green ink (0-100%)
0% = no cyan, 100% = full cyan
Magenta (M): Red-blue ink (0-100%)
0% = no magenta, 100% = full magenta
Yellow (Y): Yellow ink (0-100%)
0% = no yellow, 100% = full yellow
Black (K): Black ink (0-100%)
0% = no black, 100% = pure black

Supported CMYK Input Formats:
