NAME

       al_color_lch - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro_color.h>

              ALLEGRO_COLOR al_color_lch(float l, float c, float h)

DESCRIPTION

       Return  an  ALLEGRO_COLOR(3alleg5)  structure  from  CIE  LCH values.  LCH colors are very
       similar to HSL, with the same meaning of L and H and C corresponding to S.  However LCH is
       more  visually uniform.  Furthermore, this function expects the angle for H in radians and
       not in degree.

       The CIE LCH color space is a cylindrical representation of the L*a*b* color space.  The  L
       component is the same and C and H are computed like this:

              C = sqrt(a * a + b * b)
              H = atan2(b, a)
