CIELAB is a nonlinear transformation of RGB where the Euclidean distance between two colors is equal to their perceptual distances (for distances less than ~10 units). Algorithms that process color images often produce better results in CIELAB.

The equations implemented here come from Charles Poynton's Colour FAQ.
