LAB color space

LAB color space

La*b* system was recommended in 1976. This is a standard, approximately uniform color space. The CIELAB is organized in a cube form.

\( L^*=116 (Y/Y_n)^{1/3}-16 \)

\( a^*=500\left[(X/X_n)^{1/3}-(Y/Y_n)^{1/3}\right]\)

\( b^*=500\left[(Y/Y_n)^{1/3}-(Z/Z_n)^{1/3}\right]\)

CIE H°LC diagram displays positions of hue and chroma correlates in a polar coordinate system:

 \(h_{ab}=\displaystyle\arctan\frac{b^*}{a^*} \)

 \( C_{ab}=\sqrt{(a^*)^2+(b^*)^2} \)
