Now clear. In principle, all the necessary instructions have already been given there, I have little idea what can be added.
You need to change the 4 bytes (XX XX XX XX) responsible for the color in the specified address lines. (# FF222222, BB444444, FE111188, EE000000, …). If change on black : on FF000000, or FE000000, or 00000000, … or your other version of black.

For example:
