So this is actually measuring the difference between two colors and it assumes that the color space is 100% uniform. LCh is only a conversion from cartesian coordinates to polar coordinates, but the underlying color model is the same. $$L = L$$ $$C = sqrt{a^2 + b^2}$$ $$H = cases{ arctan(b/a) & ext{if }arctan(b/a) geq 0 arctan(b/a) + 360° & ext{otherwise} }$$ Implementation Notes:Also supports RGB, HSV, HSL, Lab, LCH, and other models. While CIELAB (L*a*b*) uses Cartesian coordinates to calculate a colour in a colour space, CIELAB (L*C*h) uses polar coordinates.
