Welcome to Pixelation!
Be more specific.
Are you looking for a good commonly used palette?
Yes, That is what I mean for colors.
My personal favourites are those of Jinn, DawnBringer and Arne.
Jinn's palette is more centered towards paintings and illustrations, rather than game graphics. Because it's most effective when you use several of it's colours, because each and every one of them depend on each other, highly. But you could definitely use them for game graphics if you really want, too.
DawnBringer's and Arne's are a lot more versatile, though. You could definitely use them for game graphics and paintings alike.
There are a lot more though, such as ptoing's, Syosa's, Night's and the palettes of so much more talented artists. The above three are just my favourite.
