What is CMYK Color Model?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It is a subtractive color model used primarily in color printing. Unlike RGB which adds light, CMYK works by subtracting brightness from white paper. Each value ranges from 0% to 100%, representing the amount of each ink color applied.

Cyan (C): Blue-green ink that absorbs red light
Magenta (M): Pink-purple ink that absorbs green light
Yellow (Y): Yellow ink that absorbs blue light
Key/Black (K): Black ink added for depth and contrast

What is HEX Color Code?

A HEX color code is a 6-digit hexadecimal representation of a color used in web design, CSS, and digital graphics. It starts with # followed by three pairs of characters (00-FF) representing the red, green, and blue components. For example:

#FF0000 = Pure Red (255, 0, 0)
#00FF00 = Pure Green (0, 255, 0)
#0000FF = Pure Blue (0, 0, 255)
#FFFFFF = White
#000000 = Black

CMYK to HEX Conversion Formula

The conversion from CMYK to HEX involves two steps: first converting CMYK to RGB, then RGB to HEX.

Step 1: 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)

Step 2: RGB to HEX

Convert each RGB value (0-255) to a 2-digit hexadecimal number and concatenate with # prefix.

Why CMYK Colors Look Different on Screen

CMYK is designed for print media using physical inks, while computer screens use RGB light to display colors. The CMYK gamut (range of reproducible colors) is smaller than the RGB gamut. This means:

Some bright screen colors cannot be accurately printed in CMYK
CMYK colors converted to HEX are approximations for digital display
Always proof print colors before final production

Frequently Asked Questions

What is CMYK color model?

CMYK stands for Cyan, Magenta, Yellow, and Key (Black). It is a subtractive color model used primarily in color printing. Unlike RGB which adds light, CMYK works by subtracting brightness from white. Each value ranges from 0% to 100%, representing the amount of each ink color applied.

How do I convert CMYK to HEX?

To convert CMYK to HEX: First convert CMYK to RGB using formulas R = 255 × (1-C) × (1-K), G = 255 × (1-M) × (1-K), B = 255 × (1-Y) × (1-K). Then convert each RGB value (0-255) to a 2-digit hexadecimal number and combine them with a # prefix.

Why do CMYK colors look different on screen vs print?

CMYK is designed for print media using physical inks, while screens use RGB light. The CMYK gamut (range of colors) is smaller than RGB, so some bright screen colors cannot be accurately reproduced in print. This conversion shows you an approximation of how a CMYK color appears in digital formats.

What is the K in CMYK?

The K in CMYK stands for Key, which refers to Black ink. It is called Key because in traditional printing, the black plate was the key plate that aligned the other color plates. Black is used because combining 100% Cyan, Magenta, and Yellow does not produce a true black, and using black ink is more economical.

What is a HEX color code?

A HEX color code is a 6-digit hexadecimal representation of a color used in web design and digital graphics. It starts with # followed by three pairs of characters (00-FF) representing the red, green, and blue components. For example, #FF0000 is pure red, #00FF00 is green, and #0000FF is blue.
