I was wondering if anyone knows where to get a good online tutorial on how to colour in photoshop.

See me and a friend have written a comic which we both think rocks out loud and before I draw it I want to learn how to colour it and make it look pretty but im poor and don't have much spare time so I can't take a class.

PLEASE HELP!

That one's pretty good, all things considered.

That should be very useful, thanks mate!

I can't wait to get this done and begin my brilliant scheme!

It might teach you the basic principle of HOW to do it in photoshop but I would really suggest not following that tutorial to any real length... the coloring, shading and even lineart are unfortunately rather bad.

Seriously, they have some pretty nice tutorials up there for a variety of art styles like cell-shading, realistic, burn/dodge whoring, the usual. There's also plenty of special effect tutorials like fire, water, ice, hair, anime eyes, and so on. Just type in "tutorial" plus whatever style you're looking for and there's bound to be something that catches your eye and/or is something you're able to do.

I have a good link to one that can be a bit troublesome to figure out at times, but the results are well worht it. I'll have to get it to you later.

really, just make one layer for lineart, and then another for color, and put the color layer under the lineart
and then color
also you know what that says for shading? The whole "use a black brush at low opacity" thing? NO
NO
also never use dodge and burn, that's not how colors work, that's not how shading works
EDIT: how to color, the right way

see the 3 divisions of color at the top-left? The yellow/orange-yellow are warm colors, obviously, if you remember your color wheel
places where light hits objects get not only "closer" to white but also achieve a more yellow hue
so highlights = yellow
and of course you see the cooler blues and purples below the warm colors, and those are the cool colors
places where light is NOT hitting an object (at least, not as much as the highlights) are shadows, and those not only get "closer" to black but also generally more blue-purple
and below the cool colors are the neutrals, which are NOT COLORS, so DON'T USE THEM when you shade (and generally you should avoid them when coloring as well, because pure black/grey/white don't really naturally occur; some exceptions to the rule are using black in dynamic shading [where pure dark black is used for all shadows, kinda like Viewtiful Joe, No More Heroes, or Hellboy] and for lineart [like in my example])
if you want to see this kind of color theory in action just go outside in the evening, generally the whole "purple shadows yellow highlights" thing is strongly intensified then (especially in the clouds)
EDIT: also if you want some examples from artists with some actual talent (i.e. not me) then I can link some

Okay devins little thing handled colors and stuff pretty well; I don't really have time to pull up images for this so a text explanation will have to do. But, as far as shading goes;

Shadings primary purpose is to convey two things: Depth and light-source. Shading SHOULD provide a sense of three dimensionalism to the art in question. Things that are further away get slightly darker and less contrasted/more blue and purple in tone. Things that are closer, more contrasted and a little bit warmer. Light source is also important; every peice should have a defined lightsource and the shading should reflect what that is. Everything from the position and color of the lightsources should be taken into account. Images may also have several different light sources so dont think you are limited to just one!!

I know the basics, i was refering to tips on how to do the more advanced things as well as advice on how to make it as proffessional as possible, but your advice helps guys and will be taken into consideration.

This all gives me a new idea for a thread that will be sort of a game and at the same time a way to share styles tips and ideas.
