Palette Address/Code

Sup. I have question… I been exploring about room hacking, but found with a problem.

Find the proper palette, when find the sprites of a game can’t find which one is the right palette.

There is way, program, wiki, list or anything to find out a game right palette?

I been trying with many programs and looks don’t find anything useful on net.

So… anyone knows if there is way to find it or must check one by one until find it?

Appreciated
