Salutations. Sorry for the bad English. I'll be brief. I wanted to start taking the first steps with using colors. Up until now I have always used very few colors and I would like to make some progress. In this portrait for example (WIP) I wanted to highlight the hair, with some red / orange tints. Similar to fire so to speak. The thing is, I have no idea where to start. I really lack the technical knowledge of the method. Can you give me any advice?
