Hi.

I'm trying to help out with an open-source game called Gearhead.



I took the above portrait, which was one of the default portraits, and made the following one in Paint.



The colors are funky on purpose.  The game makes use of SDL to do pallette swapping.  Red, green, and yellow (with blue as transparency) are the only hues that can be used for sprites and portraits. 

The images below show what colors the engine is able to recognize as different.



Is there any advice on what I should do?
