Color Depth
To reduce the number of colors in the image select the
appropriate bit count in the color depth interface. Doing so will reduce the
number of bits used for the RGB triad for color representation and will
effectively reduce the image to fewer colors.
Note the color selection is not optimized and simply
performed as a bitwise right shift of the RGB colors.
On selections of uneven number of bits the green is
provided more bits.
If 21 bits is selected
R = R>>1
G = G>>1
B = B>>1
