The red eyes really kill me. Why not use black like the original?
The Intent is not be like the original

Jokes aside, the red-eye is to achieve a good color ramp with the yellow on the face. Furthermore, the face palette is shared with some enemies and I've set not having black outlines for this hack, which inevitably requires black be replaced by color "0" (04 , or 05, 06 , 07)
Plus, Megaman can have red ears when firing from the stairs (half of the ears in red).
When on game play you barely note the face in red, in general it looks like dark lines (dark red lines).
Of course, you have the right to dislike it.
