^{*}C

^{*}h color space uses the same diagram as the L

^{*}a

^{*}b

^{*}color space, but uses cylindrical coordinates instead of rectangular coordinates. In this color space, L

^{*}indicates lightness and is the same as the L

^{*}of the L

^{*}a

^{*}b

^{*}color space, C

^{*}is chroma, and h is the hue angle. The value of chroma C

^{*}is 0 at the center and increases according to the distance from the center. Hue angle h is defined as starting at the +a

^{*}axis and is expressed in degrees: 0° would be +a

^{*}(red), 90° would be +b

^{*}(yellow), 180° would be -a

^{*}(green), and 270° would be -b

^{*}(blue). If we measure the apple using the L

^{*}C

^{*}h color space, we get the results shown below. If we plot these values on Figure 9, we obtain point (A).
