Tutorial request

I'm looking for tutorials on awesome colourings like these icons =]

I don't use photoshop (I use Fireworks 8) so I need some translatable ones m(- -)m
Any help would be great^^

Hmm.. to make it a bit more clear, I want the bright blue (or any colour) plus yellow-y effect, but also makes the graphic looks clean and smooth.
I hope it's understandable^^;
