Good day to all. I am a new member and am having problems locating info on paint mixing due to my apparent lack of proper search term usage! I am looking for a somewhat detailed description on the general procedure for mixing black and white paint and reduction when painting a black and white portrait. When I say black and white, I mean black/grey/white etc. Not black or white, high contrast work! For example, for shading, do I use various levels of grey or highly reduced layers of black transparent, etc. I'm not asking for anyone to give me a detailed lesson on years and years of their paint mixing experience, but, can someone just direct me to some threads that will give me the basics and I'll go from there! Thanks you Mark Murrieta, Ca.
