For those wishing to do pseudo art design for the MD or SMS.

The standard MD specs are (I believe) as so:
320*224 screen,
15 colours for background 1, 15(+BGColour) colours for background 0,
15 colours for Sprite palette 0 and 15 colours for sprite palette 1.
These come from a 9-bit (512 colour) palette. Each channel (R,G and B) has 3bits, or 8 levels including off. The equivalent values for these in a simple image editing program would be:
000, 036, 072, 108, 144, 180, 216 and 255 or (in hex):
00, 24, 48, 6C, 90, B4, D7 and FF
Standard SMS specs:
256*192
BG palette consists of 15(+BGColour) colours
Sprite palette consists of 15 colours
6-bit (64 colours) palette. Each channel (R,G and B) has 2 bits, or 4 levels including off:
000, 085, 170, and 255, or (in hex):
00, 55, AA and FF\

The sequence is 36 based for 9bit RGB. And if you mix Shadow and Highlight colors in the mix there's 18 coming into play.

Starting at 064? That's one hell of a shift.

Also on SMS you have 16+16 colors, plus one more as the border color. There is no shared color on the BGs, the color index 0 is always shown and the border color around the screen is set by a register and is separate from others. Sprites can only use the second palette.
