Cmyk To Hex

Converts CMYK color values to hex format for web development and design workflows. Access via MCP in Cursor or Windsurf for instant color conversion, or use the REST endpoint /v1/color/cmyk-to-hex. Input cyan, magenta, yellow, and key (black) percentages (0-100) and get precise hex codes like #FF5733. Essential for print-to-web design transitions.

API Endpoint

  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);
import requests

response = requests.get('https://tinyfn.io/v1/color/cmyk-to-hex',
    headers={'X-API-Key': 'YOUR_API_KEY'})

FAQ

How do I convert CMYK values to hex using the MCP tool?

Provide CMYK values as percentages (0-100) for cyan, magenta, yellow, and key (black). The tool returns the equivalent hex color code for web use.

What's the difference between CMYK and hex color formats?

CMYK is subtractive color for print (cyan, magenta, yellow, key/black percentages), while hex is additive RGB for screens using 6-digit codes like #FF0000.

Can I batch convert multiple CMYK colors to hex at once?

The endpoint handles single conversions. For batch processing, make multiple API calls or use MCP tools in AI coding assistants for automated workflows.

Why do CMYK-to-hex conversions sometimes look different on screen?

CMYK covers a different color gamut than RGB/hex. Some print colors can't be perfectly reproduced on screens, leading to closest-match approximations.

What CMYK input ranges does the conversion tool accept?

All CMYK values should be percentages from 0 to 100. Values like C:75, M:0, Y:100, K:0 convert to their hex equivalents accurately.
