Phthalocyanine Green YS or Yellow Shade. This is a merry, high-saturation emerald green which leans a bit more yellow. In mixes it is the queen of limes. We've used this color to make some of the highest chroma lime greens when mixed with yellow. In phthalos greens, the yellow shade and the blue shade are different pigments, though each may have some sub-varieties within the pigment code. Phthalo Green Yellow Shade, PG36, can be thought of as the yellower-green companion to PG7.
This color is very dark in masstone, but when thinned for glazes or mixed into tints it is a gorgeous chromatic green. Robert Gamblin suggested that if only PG36 had been invented earlier than the other phthalo green, PG36 would be the more popular one today. We find both greens to be indispensable for a high chroma palette.
While phthalos are less toxic than some other paints, be careful with tubes made before 1982 (or even 1986) as they may contain PCBs as a contaminant. Please also see Monona Rossol's work as well as the Artist's Guide to Health and Safety, which has information that relates to working with pigments which contain copper.
Similar to PG7, the feel of modifiers, stabilizers and extenders are often found in PG36 as well.
