Can you have more than 2 colors as your option? If you can, can you please tell me how? Cuz i looked for a way and i cant find ne thing. Thx if you can tell me lol.

You can set the gradient on color, and lay it down. Make sure you desaturate the pic though. You can do that by ctrl + u.

The hard way is to desaturate it, then put the gradient you want down, then ctrl + f, click color, and bam. Be sure to adjust the contrast though, it's boring without color.

Another way is to desaturate it, get a brush and make the opacity like 10%, then color it on your own.

aiight kool, i'll check it out. can you add me to ur msn or aim, or leave ya email in here cuz i wanna ask some other questions if thats kool wit u
