Mixed 3 slightly different palettes from traditional red, yellow, blue. The differences are from swapping a slightly different red and/or yellow.
Based on cadmium yellow, cadmium red, ultramarine blue plus white.
Note how the 3 palettes lean warm (towards orange) and have more muted greens and brownish purples. The mixed dark is more a brown than a black.
Contrasted with another palette based on cyan, magenta, yellow (CMY) plus white, where the "cyan" is phthalo blue, a green-leaning blue. Instead of browns, we have violets. Also, the greens aren't muted.
Traditional palettes can be useful for more natural-looking colours in landscapes, portraits etc.
I think the easiest way to think of it, is that if want browns, look at using a red which leans orange. If don't want brown but want violets, avoid red & use magenta (aka red purple).
Hundreds of colours can be mixed from a limited palette of 3 colours. Will have a different gamut though, depending on which "primaries" are chosen to mix the other colours.
