HEX CMYK Converter

HEX to CMYK refers to the process of converting a color from the HEX (Hexadecimal) format to the CMYK (Cyan, Magenta, Yellow, Key/Black) format.

What is HEX?
HEX is a hexadecimal color code used to represent colors in digital design, composed of six characters: #RRGGBB, where:
RR represents the Red component in hex (00 to FF),
GG represents the Green component in hex (00 to FF),
BB represents the Blue component in hex (00 to FF).
What is CMYK?
CMYK is a color model used in printing, where the colors are represented by Cyan (C), Magenta (M), Yellow (Y), and Black (K) components.
The values in CMYK are expressed as percentages ranging from 0% to 100%.
Steps to Convert HEX to CMYK:
To convert a HEX color to CMYK, follow these steps:

Convert HEX to RGB:

The first step is to convert the HEX code into RGB values.
For example, #FF6347:
Red (R) = FF (hex) → 255 (decimal)
Green (G) = 63 (hex) → 99 (decimal)
Blue (B) = 47 (hex) → 71 (decimal)
So, RGB = (255, 99, 71).
Normalize RGB values:

Convert the RGB values into the range of 0 to 1 by dividing each by 255.
R' = 255 / 255 = 1.0
G' = 99 / 255 ≈ 0.388
B' = 71 / 255 ≈ 0.278
Find the maximum and minimum RGB values:

max = max(R', G', B') = 1.0
min = min(R', G', B') ≈ 0.278
Calculate the Key (Black) value (K):

K = 1 - max(R', G', B') = 1 - 1.0 = 0.
If K = 1, it means the color is pure black, and the CMY values will be zero.
Calculate the Cyan (C), Magenta (M), and Yellow (Y):

If K < 1:
C = (1 - R' - K) / (1 - K) = (1 - 1.0 - 0) / (1 - 0) = 0
M = (1 - G' - K) / (1 - K) = (1 - 0.388 - 0) / (1 - 0) ≈ 0.612
Y = (1 - B' - K) / (1 - K) = (1 - 0.278 - 0) / (1 - 0) ≈ 0.722
Convert to percentages:

C = 0%
M ≈ 61.2%
Y ≈ 72.2%
K = 0%
Final CMYK:
So, the CMYK equivalent of HEX #FF6347 (or RGB(255, 99, 71)) is:

C: 0%
M: 61.2%
Y: 72.2%
K: 0%
In Summary:
The HEX to CMYK conversion involves:

Converting the HEX value to RGB.
Normalizing the RGB values.
Using formulas to calculate Cyan, Magenta, Yellow, and Black percentages.
