This table shows a palette of 16 colors that I currently use for my internal projects. It's similar in concept, but not identical, to a color palette I used for the first computer game I've developed, back in 1994. Back then, I just took the standard EGA 16 colors palette and replaced dark cyan by peach; the current table is the result of many years of doodling, and is adjusted to fractions of 6.
It's also similar, but not identical, to Wad's Optimum 16 color palette, which was independiently developed as part of a class assignment and following different goals. The colors in my table are in the same order as those in Wad's palette.
