About CMYK to RGB Converter

Input an CMYK value like 100%, 0%, 0%, 0% and Diversify India’s CMYK to RGB converter will convert this value to an RGB color like rgb(0, 255, 255).

CMYK color parameters are Cyan, Magenta, Yellow, and Key. The output RGB color parameters are red, green, and blue.

Why Convert CMYK to RGB?

Converting CMYK to RGB is essential for digital applications where colors need to be represented in terms of red, green, and blue light. While CMYK is mainly used for printing, RGB is popular in web design, graphic design, and image processing because it supports transparency through the alpha channel. This conversion ensures accurate color representation across different media.

How to Convert CMYK to RGB

To convert CMYK to RGB, you need to transform the cyan, magenta, yellow, and black components into red, green, and blue components.

  1. Extract the values for Cyan (C), Magenta (M), Yellow (Y), and Black (K) from the CMYK code.
    • Example: 60%, 20%, 80%, 20% gives C = 60%, M = 20%, Y = 80%, K = 20%.
  2. Convert the CMYK values to a range of 0 to 1 by dividing by 100.
    • C = 60% / 100 = 0.6
    • M = 20% / 100 = 0.2
    • Y = 80% / 100 = 0.8
    • K = 20% / 100 = 0.2
  3. Calculate the RGB components:
    • R = 255 × (1 – C) × (1 – K)
    • G = 255 × (1 – M) × (1 – K)
    • B = 255 × (1 – Y) × (1 – K)
  4. Example Calculation:
    • R = 255 × (1 – 0.6) × (1 – 0.2) ≈ 82
    • G = 255 × (1 – 0.2) × (1 – 0.2) ≈ 163
    • B = 255 × (1 – 0.8) × (1 – 0.2) ≈ 41
  5. Combine the RGB values:
    • Example: rgb(82, 163, 41)
