This is my favourite greenish yellow that is made from Pigment Yellow 175 and consequently has the highest lightfastness of any of the yellows made from organic pigments that don't contain toxic cadmium. It is a level of lightfastness higher than Hansa Yellow Light (PY3) that is the other common Lemon Yellow pigment. This paint mixes well with other high quality watercolour paints and makes bright greens when mixed with greenish blue pigments like phthalo blue (PB15:1) and phthalo green (PG7). The oranges it makes when mixed with red pigments tend to be on the dull side because of the slightly greenish tone of PY175. The brightest orange colours can be made using DS Hans Yellow Deep with Pigment Yellow 65 mixed with red pigments.
