For some reason I tried some floral drawings, of different shapes, and I also used mixtures of different colors to produce hues of green. The first page - it’s a mix of the cobalt blue (PB 28) and cadmium yellow medium (PY 35). On the second one there is ultramarine (PB 29) for the blue color and the same yellow paint. To me, it seems the difference is very little but I’ve got the color closest to the ‘normal’ green using Cobalt rather than ultramarines. The latter gave either to yellowish to olive hues or too blueysh
