Both use Hue + two components, but they model brightness differently. HSL's Lightness ranges from black (0%) through the pure color (50%) to white (100%). HSV's Value represents maximum brightness at 100% with Saturation controlling how vivid it is. Designers often prefer HSL; some image editors use HSV.

CMYK (Cyan, Magenta, Yellow, Key/Black) is the color model used in print. Converting RGB screen colors to CMYK gives you approximate ink values for physical printing. Note: exact CMYK depends on your printer's ICC profile — these values are a standard approximation.
