. . . at one time.
Sony MSX palette ( http://en.wikipedia.org/wiki/MSX
), 15 unique colors, restrictions neglected and the grid not "kept to".
I really liked the colors (although the palette lacks deeper and darker hues to build proper ramps on) and so decided to give it a go. 7, maybe 8 hours of deep meditation.
It probably looks like Ptoing went crazy in places, and yes, it was inspired by his MSX attempts, but I wanted to do something less hardware dependent. I might as well do something in keeping with the restrictions at a later basis.
