Core Algorithm/Logic

The core algorithm or core logic to convert HEX to CMYK is based on the RGB color model. The RGB color model combines red, green, and blue light to create a wide range of colors. To convert RGB to CMYK, we first need to convert RGB to CMY (cyan, magenta, yellow) and then apply the K (black) value based on the brightness of the color. The formula for conversion is as follows:

C = 1 - R
M = 1 - G
Y = 1 - B
K = min(C, M, Y)
C = (C - K) / (1 - K)
M = (M - K) / (1 - K)
Y = (Y - K) / (1 - K)

How to Use the Tool

Using our HEX to CMYK converter is easy. Here's a step-by-step guide on how to use it:

  1. Input or paste your HEX color code in the input box provided, like this: #ffd500.
  2. Click the "Convert" button to convert the HEX color code to its corresponding CMYK color code.
  3. You can then copy the CMYK color code or click the "Copy" button to copy it to your clipboard.

Examples in Python, C, JavaScript, Java, and PHP

If you're a developer, you can use our tool in your application by incorporating the following code in any of the programming languages mentioned:

Python

def hex_to_cmyk(hex):
    r, g, b = tuple(int(hex[i:i+2], 16) for i in (0, 2 ,4))
    c = 1 - (r / 255)
    m = 1 - (g / 255)
    y = 1 - (b / 255)
    k = min(c, m, y)
    if k == 1:
        return 0, 0, 0, 100
    return (round((c - k) / (1 - k) * 100),
            round((m - k) / (1 - k) * 100),
            round((y - k) / (1 - k) * 100),
            round(k * 100))

hex_code = "#ffd500"
