Table entries that are don’t cares (indicated by gray shading) are written as 0, but can be written as 1. If the
pixel value of 010b from the example Red grayscale LUT is overwritten, it will then become the following:
const unsigned long rgb_gs_lut_r[32] =
{
// ALL 0 , 25% , EXAMPLE , 50% , 50% , 75% , 75% , 100%
