I finished this chart tonight and I felt like I was painting the same exact swatches 3 times over. If you look at the last three columns on this chart they are all almost exactly the same. The mixtures are red scarlet with veridian, then manganese blue, then ultramarine deep.
I think that with different amounts these color mixtures they could become different as this is seen on the previous charts I have done, but its interesting to note how Veridian, Manganese, and Ultramarine can be interchangeable with Red scarlet.
