1. Open up your clean image (see PS Tutorial 1 for cleaning) and make absolutely
sure there are no more changes you want to make to the lineart. Good? Okay. Then, I want you to go to Image > Mode > RGB color
(or else this next step won't work), and then go to Layer>Duplicate Layer to get a duplicate of the lineart.
2. Open up your layers palette and select the layer you just duplicated (usually the default name is "background copy"). Go to its menu and
find "multiply".
Your image's lines should appear darker after this is selected. What's happening is, PS is taking any color in your image and copying it about 50% darker on
the second layer. The trick with this technique is that it doesn't multiply the white color, so you're left with just the lineart on the second
layer. This allows you to color behind the lines instead of over them - like this:
3. You have the option to erase anything on the original layer to make the image look like it did before, but be forewarned:
it makes the layer reeeeally hard to color later on, especially if you're using the select tool to find your areas to color.
Also, always double-check to make sure you're coloring on the original first layer; if you're coloring the second layer, there will be
many complications, trust me ^^.
That was simple too, huh? ^^ If you need any extra help, email me!
