If I understand what your asking....
I dont think the color change mod in that pack above affects set npcs' like say, Shaundi or other named ones. Only
the general spawn gang members in cribs and on streets (saints).
Yes, it is random colors they can spawn with. I've only used the rainbow one and there seems to be some rotation of colors. I've
not paid a lot of attention to that though. I use the strippers/gimps/bikers/ and a morningstar for gang members , all female.
I mixed the options in GangPlusOne with Gandalfs homies mod so I could have the cowgirls (I think a member of the hoes 'faction")
without being forced to try to complete activities I can not seem to achieve to unlock them in GangPlusONe.
Sorry, wandered there probably into info you didn't need.
I can't comment on contents of that xtbl and would be probably more baffled. Maybe try asking in GangPlusOne thread on ideas for adjusting that
table.
encogen is the mod author he checks in pretty regular .He's the one to ask for sure. Or send him a PM (conversation on this board) message.
