Yes, here we go ...
For this first sketch, I use the traditional triad with colors from Rembrandt. I use pan paints of their 48-color box.
The colors used are:
- Gamboge: PY150 + PO20
- Cadmium Red Light: PR108
- Ultramarine Blue: PB29
As you can see, the slightly warm red and the warm yellow produce beautiful shades of orange, however the violets are duller in the mix of cadmium red with ultramarine, I had hoped for better, because to get a beautiful purple it takes a cold red and here the red is a bit warm, almost neutral.
The mixture of ultramarine blue (warm) and gum gut gives duller greens varying from olive green to a slightly tarnished Hooker green.
Here is a small study of a sunset with a solitary fisherman.
I am mostly focused on the sky, which has at 5 glazes in places, the sea has only 3 and the rocks only 2.
I observe, that by mixing the 3 colors, we get beautiful blacks.
I would have liked to get shades of turquoise for the waves, but it is impossible to achieve this color with a warm blue and a warm yellow, I would have needed a cold version of the two colors.
This demonstrates the limit of the triads if one wants to obtain almost all the colors with mixtures. With 6 primary colors, a cold version and a hot primary, we can get closer.
