mix oil to match pastel

A couple days ago I posted the pastel study for an 18 x 18 inch oil painting. Here is what I did to mix the colors for the oil painting and insure that I got the same color palette as my study:

1. I sampled pastels I used in the color study by applying a swatch on a Viva paper towel. Then, I referred to my Richard Schmid color charts.

2. I mixed oil paint on my palette until I felt it matched the color used in the pastel. In this case, the Schmincke yellow matches the color on the chart made of Cadmium Yellow Light, Cad Red and White.

I could have used trial and error to mix the yellow but this is the reason I spent days making the color charts. Very helpful!
