So if there are any specific ones you're interested in the colours for, I suggest checking 2nd ed to see if they were in there. Barik Farblast had a yellow and grey uniform as I recall, for example, though I can't remember what team he was from... Dwarf Warhammers perhaps?
The Barik Farblast illustration had black and white as his uniform with small areas of yellow details, pretty good looking colour scheme really.
As to painting stars it depends on what you want to use them for. Is it as a centrepiece for a specific team or a general star player that can be used for multiple teams?
if it they are to be used for 1 specific team then I often use the team colours but switch them up a bit. Say the team strip was red shirts and white shorts you would reverse it. Alternatively add lots of extra details like coloured borders or gold metal bits as opposed to silver.
For a generic star that can be used for multiple teams then go for something quite colourful so they will stand out in whichever team. Googling the star player will often get you some interesting colour schemes and you can rip them off.
