Thanks!

Sorry, but where did you find that 4th color,
robotriot? If you mean the outline, I wouldn`t count it in, as everything in the picture has its own. If, in turn, transparency = outline, it has 3 colors + transparency.
Honestly, I`ve been trying my whole life to make a game, even a simple one; unfortunately I`m just a lazy person.

That PixelBoy-thing rocks! It has no such limitations and a palette of 5 colors!
