CMYK to RGB Converter

How to convert CMYK to RGB?

CMYK (Cyan, Magenta, Yellow, Black) is a subtractive color model used in color printing. RGB (Red, Green, Blue) is an additive color model used in digital displays. To convert CMYK to RGB, use the following formulas where C, M, Y, K are in the range 0-100% and R, G, B are in the range 0-255:

CMYK to RGB Conversion Formula

R = 255 × (1 - C/100) × (1 - K/100)

G = 255 × (1 - M/100) × (1 - K/100)

B = 255 × (1 - Y/100) × (1 - K/100)

What is CMYK color model?

CMYK is a subtractive color model used in color printing. It stands for Cyan, Magenta, Yellow, and Key (Black). Colors are created by subtracting varying percentages of light. It's the standard for printed materials because it accurately represents how inks combine on paper.

What is RGB color model?

RGB is an additive color model used in digital displays. It stands for Red, Green, and Blue. Colors are created by adding different intensities of these three primary colors of light. Each color channel ranges from 0 to 255, allowing for over 16 million possible colors.

Why is CMYK to RGB conversion important?

Converting CMYK to RGB is essential when adapting print designs for digital use. Since CMYK is optimized for printing and RGB for screens, this conversion ensures colors display correctly on websites, apps, and digital media. However, note that some CMYK colors cannot be accurately reproduced in RGB due to different color gamuts.

Is CMYK to RGB conversion accurate?

CMYK to RGB conversion is mathematically straightforward but may not always produce visually identical colors. CMYK has a different color gamut than RGB, meaning some printed colors cannot be perfectly reproduced on screen and vice versa. Professional color management systems use ICC profiles for more accurate conversions.
