CIELCh (Lightness, Chroma, hue) is a cylindrical representation of CIELab, analogous to HSB or HSL.  The hues at the four axes (0, 90, 180, 270°) are the Lab primaries red, yellow, green, and blue.

Enter LCh value ranges (L 0 to 100, C 0 to 100, h 0 to 360°).  Ranges may be in descending order.  The sign of the increment is insignificant, but it must not be zero.
