Cadmium Red Deep Hue, Cobalt Blue Hue, Cadmium Yellow Medium Hue, Hooker's Green Hue Permanent, and Titanium White. I really like this paint. It's nice and thick and creamy and mixes beautifully.
I'll write more later about exactly how to mix tons of colors and shades, (right now I need to get to work) but I wanted you to see these ACEOs. All of the colors you see on these four little paintings were made with the five colors you see above.
