Test trying to make something passable looking with that awful 4 color CGA palette. 250x250 pixels. Character is Parker, from Wildbow's Pathquest, a 1940s physics student.
yeah, technically the CGA palette is 16 colors, with only 4 being able to be used at any one time. Many systems only had 4 sets of 4 colors allowed; the white-cyan-pink-black, yellow-green-red-black, and a darker version of those 2.
CGA could have looked much better, but its the nature of all these systems that compatibility of the colorschemes was poor, so a lot of CGA just fell into the 'lowest common denominator' of the default palette, the one I used.
