RGB to HSV
The CMYK (Cyan, Magenta, Yellow, blacK) is the color for printers,
well the ones that use 4 colors. When using this conversion it might
not be 100% accurate because of the difference in medium, RGB is
used on monitors/screens, where as CMYK is only used on printers,

Try it by entering the RGB values from 0-255 and press 'Convert to CMYK'.
