Just having fun with many colors in my studio, 2 days to do this, ala prima. This is my present palette, today's modern colors & has been for about a year now. My new choice for yellow here is named "Chrome Yellow Medium", it was very much in use before cadmium yellow was invented, I needed to adjust the value using white to be same as cadmium yellow pale.
The outer circle consists of 3 primaries, alizarin crimson, chrome yellow medium, ultramarine blue, plus secondary & tertiary colors.
The 2nd inner color wheel consists of semi-neutral colors.
The 3rd inner color wheel consists of neutral colors.
This is about to change eventually to my using an "old world color palette"?, I'm now working on this color wheel.
