Mixing Raw Sienna and Phthalo Green

The full range, Raw Sienna to Phthalo Green
Ratios are parts by volume, the way you would put them out on a palette.
These two are close enough on the color wheel that they never cancel. Every mixture between them keeps its saturation, so this is a pair for building color, not for knocking it back.
The same range with white added
Two parts titanium white to one part of the mixture above. White lifts the value but also takes the chroma down, which is why a tint is never simply a lighter version of the same color.
The same range as a watercolor wash
Roughly one part paint to two parts water, over white paper. Remember that watercolor dries up to about thirty per cent lighter than it looks while wet.
Phthalo Green is much the stronger of the two. The ratios above are by volume, so the first step away from pure Phthalo Green already changes a lot less than the last step towards it. Put out less than looks right and work towards the color; going back costs far more paint.

The transparent cousin of ochre. Beautiful as an underlayer that keeps showing through.
Very strong and artificial in tone. Tame it with red or with an earth color.
