This time, again, two combinations. I believe the hues are very nice and calming. I used yellow ochre as the yellow color (PY 43, PY 1). On the upper part, the cobalt blue (PB 28) is used, on the lower part - it's ultramarine (PB 29).
Again, mixing some colors to get greens: 1) cobalt blue (PB 28) plus cadmium lemon (PY 35); 2) ultramarine (PB 28) and cadmium yellow. Didn’t see much difference. In the first case there seem to be more hues, though. Funny, cadmium yellow medium and cadmium lemon have the same label: PY 35
