I've found what the autocolor entries effect for this dbf file. I've asked a few patchers what the values effected but nobody knew. So I experimented when creating some new uniforms. These entries effect the accessories (arms, legs, socks, etc.) when using the TEAM colors.
AUTOCOLOR - primary team color for all accessories.
AUTOCOLOR2 - secondary team color for double rubberbands, two color team knee pad and two color team calf accessories.
AUTOCOLOR3 - third color when using three color team socks.
Using Memphis as an example:
entry - color - decimal value - hex value
AUTOCOLOR - light blue - 6915522 - 6985C2
AUTOCOLOR2 - off white - 16119285 - F5F5F5F5
AUTOCOLOR3 - medium blue - 5074580 - 4D6E94
