Wow, this makes things a whole lot easier thanks for the tip. Now I won’t have to have all these layers.

@zippysqrl  
I want to grab the characters individually most of the time, though, and my pencil sketch linework scans in with too much clutter for that to work unless I block it out first.

Ctrl+Click the image preview on the layer in the layer list.
 
My method of colouring and shading is whack, so many folders and layers e.e  
Also, don’t forget about layer clipping, you can constrict your shading/lighting layers to only affect one layer/folder if you clip them(just like colouring within a selection area).

@zippysqrl  
basically I have my lines, then I block out my characters on a non-visible layer so I can quickly wand-grab out their entire profile with a single click whenever I want, then add a multiply layer for colors. If I’m so inclined, I’ll also add another layer or two for shading and highlights (usually just a light matching color tinted airbrushing) and another hidden layer with references if I need ’em.

@Keith Mowz  
That also works, providing your colour layer is just ONE layer. Alternatively, if you work in an application that supports layer modes on folders, you can set the folder to multiply and put all the colour layers inside that.  
The multiply mode acts as actual multiplication(just with colours), so it doesn’t matter whether it’s the colour layer/folder or line layer on top, it’ll multiply one with the other. Like xy or yx, you’ll get the same result regardless.  
Also if you want to be technical, it multiplies the individual channels (Red, Green Blue) separately, treating each one as a 0 to 1 scale, so you can imagine colours like red being [1,0,0], blue being [0,1,0] and green being [0,0,1]. Full white is [1,1,1] and black is [0,0,0], so if you were to multiply red with white you’d have [1,0,0] x [1,1,1], the result being [1,0,0], because 1x1 is 1 and 1x0 is 0, but if you multiply red with black, you have [1,0,0] x [0,0,0], so the result is gonna be [0,0,0], black. You can imagine the result for everything in between for the gradient from black to white.  
Eh, Wikipedia probably explains it better, it also covers the other layer modes if you’re interested :D

@zippysqrl  
That’s probably easier or more effective than how I do it, I might have to experiment.
 
Normally I put the color layer as the one set to multiply with the lines being a solid layer at the bottom.

@sub06905  
Most programs come with layer functionality, this provides the ability to colour BEHIND the lines of a drawing, by having the line layer on top and setting it to layer mode “multiply” you can colour underneath without having to worry about getting those ugly white bits between the colouring and the lines

@zippysqrl  
Layers?

<Layers.

She is so tiny

Yep.
 
That’s a Pony alright~

Tiny horse. Check
 

Can I pet the pony? :D

neat.
