ookay so, ill write a tut on multicoloring too, since many people dont know how to multicolor stuff
1. get a new doc, i used size 400x150
2. do ur brushing and stuff, and flatten the image
heres what ive got

3.rename layer background to layer 0, then dublicate ur layer a fev times, i dublicated 3 times(i ended up with 4 similar layers)
4. hide the top (in my case 3) layers
5. go to layer>new adjustment layer>color balance, and just color it
heres what ive got at this point

6. merge color balance and layer 0, now u have some(my case 3) grey layers and 1 colorized
7. now repeat 5-6 step for each layer, now u should have 4 colorized layers, i have a blue, red, yellow and green
heres my current layer palette

8. then hide all layers except the bottom two, so in my case i will erase the red, where i want green to show up, with a soft, large brush
heres what ive got

9.merge the bottom 2 layers, and unhide the next layer and erase that a bit too, heres what ive got now:
looking pretty crappy, i had bad color choices, u get better colors!
10. now again merge the bottom 2 layers, unhide the next layer and erase around that, and merge it, keep doing this until u have only 1 layer
11. Now u have a multi colored layer O_o
heres mine

looking pretty crappy, but thats just cuz i had bad color choices, they shouldnt be so different, and 4 diff colors may be too much.

anyways this is just my way to multicolor stuff, use this or some other method :blink: hi
