[Coco] OS9 Background Palette

[L. Curtis Boyle]

Border color is independent of other colors, so you just set the border to any of the 64 colors available ('$1b 34 c' is the escape sequence to set the border).
For foreground and background colors - you set up the 2/4/16 palette registers (depending on tex/graphics mode) to whatever colors you want from the 64 available, and then you can set the foreground and background colors to any of those 2/4/16. '$1b $31 p c’ (where p is the palette register 0 to $F, and c is the color 0 to $3F) is used to set the palettes, and then which palette # you are using for foreground and background, you use ‘$1b 32 p’ for foreground, and '$1b $33 p’ for background (p being the palette register 0 to $F).
