This is so a simple thing, but I can’t find the way to change the color of my drawing lines into a other color. I draw with blue and now a wan’t to chance it in black but I don’t know how I can do it.
Can you help me guys, I’m a little embarrassed for that.
Did you paint the lines on a separate layer?
If so, basically all you have to do is use HSV adjustment filter (Ctrl+U) and lower the value until the lines are black.
It’s also very easy to shade them with a brush by locking the alpha of the layer (or enabling “preserve alpha” of the brush tool).
If it’s not a separate layer, you made your life a lot harder. Depending on how the rest of the layer looks it might be possible to separate/mask them nicely in a few steps (like color to alpha and adjust levels of the resulting alpha), otherwise it gets labor-intensive…
