HSL to RGB. It takes slightly less logic to convert HSL back to RGB than the opposite way. Since we’ll use a range of 0–100 for the saturation and lightness, the first step is to divide them by 100 to values between 0 and 1. Next, we find chroma (c), which is color intensity, so that’s (1 - Math.abs(2 * l - 1)) * s. 3. Write a function RGBtoCMYK(r, g, b, c, m, y, k) that receives RGB values as input parameters, and returns CMYK values as reference parameters. So far my code reads in the numbers from the array but I cant figure out how to use the given formulas to change the data from RGB colors to CMYK colors. Any kind of help is appreciated. Thanks a lot.

Convert any RGB value to its Hex color code, along with corresponding HSL, HSV and CMYK values (including HTML/CSS values).

The short answer is, converting Munsell codes into RGB involves interpolation of empirical data in 3D that is highly non-linear. The only data set that is publicly available was collected in the 1930's. Free or inexpensive programs that I have found on the net have proved to be flawed. I wrote my own.
