TUTORIAL digital colors

Well,
I wanted to do some kind of "Tutorial" for show you how I made colors...
Maybe I am not a expert or professional in colors, but of the bit that I know I want to show for you can learn or simply see my technique....
I know that my technique not is perfect and I have to improve a lot ( I'M JUST A PRINCIPIANT ON PAINTER), but not matter, the important is that I want to show you and help you if you need some kind of help in digital colors...

I haven't found one "correct" technique for make colors, I have experimented with several methods but i haven´t found the mine....this tutorial is just how i did this image (elf and barlog:[link]) but my way for to do colors frecuently can variate ...

I hope you like it and you get fun!!!
