After the first length indicator comes another integer, also indicating length. Useless, but it's there.<br />Then two bytes; palX, useful for the PS version only (always 0).<br />Then two bytes again; palY, useful for the PS version only (always 480).<br />Then two bytes; number of colors in the palette (always 256).<br />Then two bytes; number of palettes.<br />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 Blue, 5-bit Green and 5-bit Red).

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.
