Common CMYK to HEX Conversions

Primary Print Colors

C:100 M:0 Y:0 K:0 → #00FFFF
C:0 M:100 Y:0 K:0 → #FF00FF
C:0 M:0 Y:100 K:0 → #FFFF00

Rich Black & Neutrals

C:75 M:68 Y:67 K:90 → #000000
C:0 M:0 Y:0 K:50 → #808080
C:0 M:0 Y:0 K:20 → #CCCCCC

Understanding the Conversion Process

Converting CMYK to HEX involves first transforming CMYK to RGB, then RGB to HEX. The formula is:

CMYK to RGB: R = 255 × (1 - C/100) × (1 - K/100)
G = 255 × (1 - M/100) × (1 - K/100)
B = 255 × (1 - Y/100) × (1 - K/100)
RGB to HEX: Convert each RGB component to hexadecimal and concatenate

JavaScript Implementation

Here's a JavaScript function that converts CMYK to HEX:

// CMYK to HEX converter function
function cmykToHex(c, m, y, k) {
  // Convert CMYK to RGB
  let r = 255 * (1 - c/100) * (1 - k/100);
  let g = 255 * (1 - m/100) * (1 - k/100);
  let b = 255 * (1 - y/100) * (1 - k/100);
  
  // Round RGB values to integers
  r = Math.round(r);
  g = Math.round(g);
  b = Math.round(b);
  
  // Convert RGB to HEX
  const toHex = (value) => {
    const hex = value.toString(16);
    return hex.length === 1 ? '0' + hex : hex;
  };
  
  return '#' + toHex(r) + toHex(g) + toHex(b);
}

Print to Web: Important Considerations

Color Gamut Differences

CMYK is a subtractive color model used in print, while HEX represents colors in the RGB additive model used for digital displays. The CMYK gamut is smaller than RGB, meaning some web colors cannot be accurately reproduced in print. Our converter provides the closest possible match, but be aware of these limitations when working across mediums.

Rich Black vs. Web Black

In print, a “rich black“ (typically C:75 M:68 Y:67 K:90) creates a deeper black than using K:100 alone. However, on the web, black is simply #000000. Similar discrepancies exist for other colors, which is why professional designers often maintain separate color palettes for print and digital projects.

Pantone and Spot Colors

If you're working with Pantone or other spot colors, be especially careful when converting to web colors. Spot colors often have unique properties that cannot be fully captured in RGB/HEX. For the best results, refer to official Pantone color bridge guides that provide validated HEX equivalents.
