Sum of absolute differences in luv colorspace

The color difference can be calculated using the Euclidean distance of the (L*, u*, v*) coordinates. It follows that a chromaticity distance of $${\displaystyle {\sqrt {(\Delta u')^{2}+(\Delta v')^{2}}}=1/13}$$ corresponds to the same ΔE*uv as a lightness difference of ΔL* = 1, in direct analogy to CIEUVW.
