| − | [[Category:Hacking Information]] | |
| − | A selection of colours which is used in an image. Rather than defining a colour for each individual [[pixel]] (such as in 24-bit colour images), palettes are used to link pixels to colour data by way of an index reference. Graphics in [[Sega Genesis|Megadrive]], [[Master System]], [[Game Gear]] and [[GameBoy Advance]] games all use palettes.

| − | ===Megadrive Palette===
| |
| − | Consists of 16 colours, each represented by two bytes (four [[Nybble|nybbles]]) in the format '''0B GR''', where B = blue; G = green; and R = red. The B, G and R can be any of the following values:
| |
| − | *0 = 0
| |
| − | *2 = 32
| |
| − | *4 = 64
| |
| − | *6 = 96
| |
| − | *8 = 128
| |
| − | *A = 160
| |
| − | *C = 192
| |
| − | *E = 224
| |
| − | *(and in rare cases, F = 224)
| |
| − | Pixels reference these 16 colours using a single nybble. '''0''' refers to the 1st palettte entry (which is normally transparent), '''1''' refers to the second entry, and so on.

| − | ===Master System Palette===
| |
| − | Consists of 16 colours, each represented by eight [[Bit|bits]] (a single byte) in the format '''00BBGGRR''', where BB = blue; GG = green; and RR = red. The BB, GG and RR can be any of the following values:
| |
| − | *00 = 0
| |
| − | *01 = 85
| |
| − | *10 = 170
| |
| − | *11 = 255
| |
| − | As such, the highest palette value is '''00111111''', which is '''3F''' when converted to a byte.
