=== Section 4: Palette ([[User:Terence Fergusson|Terence Fergusson]] & [[User:Myst6re|myst6re]]) ===
The following is an overview of the palette data.

After the first length indicator comes another integer, also indicating length. Useless, but it's there.
Then there's one more integer; unknown purpose.Then one bytetwo bytes; unknown (blank often).Then a wordtwo bytes again; unknown (always 480).Then two bytes; number of colors in the palette plus one. No idea why. You can work numcolors out from the section length, but FF7 stores it anyway; why add one? Dunno(always 256).One more byteThen two bytes; unknown (blank often)number of palettes.
Then the actual palette data.
Each palette entry is a 16-bit color. This is unusual - normally palettes store as high quality data as possible, usually 24/32 bit. However since FF7 only ever runs in 16 bit I guess there isn't much point storing any other kind of data. Actually, the data is 15-bit (1 mask bit, 5-bit RedBlue, 5-bit Green, and 5-bit Blue, and 1 mask bitRed).

Palettes generally contain a number of colors that's a multiple of 256. This is because the palette is split up into 256-color 'pages' internally. So the first color is page 0/color 0. Color 256 is page 1/color 0. Color 628 is page 2/color 116. You'll see why in the [[FF7/Field/Background|background]] section.
