WOW, thats a lazy way to ask for help. :
What do you need help with?
Next time please list here in the content box as well what you need help with and be alittle more specific, list things that you have tried and what your having problems with, don't make it look like your to lazy to post, this will help get you the best results to what you are needing help with. Your lucky I'm a nice guy and that this is the best Mugen forum out there, because most forums would not have even answered this request, they would have flamed you and went on about others things and would have completely over looked you. SO, I'm guessing by the name of the heading that your needing help with changing colors of a character. Right?
If you are trying to change the colors of a character sprite that you did not create, then you will need to learn how to use FF (Fighter Factory) or PSP (PhotoShop Pro) casue you need to change the color by modifing the characters palette (which would be the easier way to do this) which are in the characters folder, these are the files that have an .act extention on them. You can use FF to open up the character and then there is a "tool" in the Tools option with a palette editor built in. Experiment with that, there are tons of You Tube videos that will show you how to use this feature. Heres one I pulled up for you:How To Palette Edit sprites on Fighter Factory
Or you could simply ask someone to do it for you. (That would be, by far, the easiest way to do it)
Now I didn't mean to offend you if I did and I'm not picking on you, but I think you would need to know how to better ask for help for next time. I hope what I have posted for you helps, if you need further assistance, you know what to do.
