Thank you very much @kookyan for such comprehensive tutorial, it is like math when it is not enough to repeat what you already know, even though I am drawing and painting for a long time but every time I have a pick at color wheel, and every time I have to think if that is warm of cold color. Of course once painting is ready it looks like easy and straightforward but the way to it always needs a confirmation if you are using the right thing because you do not want to lose your work and re-start from beginning.

I really appreciate you for taking time and presenting all tips and tricks in one post, I think many artists will find your post informative and helpful :)
