    • outOfGamut

      protected static boolean outOfGamut(NamedColorSpace colorSpace, float[] component)
      If epsilon is 0, we get the best rendering with OK LCH: the shape is a triangle with a straight line from the bottom left to the right, and a curved line from the right to the top left. (as shown below).

      However, with epsilon 0, pure white color converted from sRGB to Display P3 is out of gamut, because the converted color value is slightly greater than 1.0.

     |         ----
     |    ----
     +----

      If epsilon is too large, we get wiggles in the OK LCH rendering: the shape wiggles at the bottom left before it goes to the right. The curved line from the right to the top left is still good.
