Hey guys, I am trying to make the colors for the red and blue of spider-man, and I honestly didn't think it would be so hard to get a primary colors down! I have comart colors, and the red of wicked colors, any idea on how to mix out of those colors to get that rich red and blue? I can't seem to get the right warmth, or tone at all. ALSO: when doing a color portrait, should i shade in blacks? Or shade in lighter shades of the colors i will be working with?
