CMYK to RGB Converter

How It Works

Common Use Cases

Code Examples

function cmykToRgb(c, m, y, k) {
  // Convert percentages to 0-1 range
  c /= 100; m /= 100; y /= 100; k /= 100;

  // Calculate RGB
  const r = 255 * (1 - c) * (1 - k);
  const g = 255 * (1 - m) * (1 - k);
  const b = 255 * (1 - y) * (1 - k);

  return {
    r: Math.round(r),
    g: Math.round(g),
    b: Math.round(b)
  };
}

// Example
cmykToRgb(100, 0, 0, 0);  // Pure cyan → {r: 0, g: 255, b: 255}
cmykToRgb(0, 0, 0, 100);  // Pure black → {r: 0, g: 0, b: 0}

Tips & Best Practices

• Use color profiles for professional accuracy
• Simple conversion is approximate, not exact
• Convert CMYK images to RGB for web use
• Test conversions with known color values
• Consider using color management libraries

Common Mistakes to Avoid

• Expecting exact color match
• Using CMYK images on web (not supported)
• Ignoring color profiles for critical work
• Wrong percentage ranges (0-1 vs 0-100)
