Rublev makes several varieties of Lead-Tin Yellow. This is a pale yellow at a high lightness, but not as light as their Lead-Tin Yellow Light, which is almost ivory. There is also a Lead-tin yellow dark, which is slightly oranger. This paint is made of lead-tin oxide and also lead stannate and bound in linseed oil. A similar paint is Michael Harding’s Lead Tin Yellow Lemon. At first blush the Rublev version looks a bit higher chroma. This is a very smooth color that does tend to have some separation with the oil, which is to be expected. To compare it with another color with which painters might be familiar this variety of Lead-Tin Yellow (Type I) is higher in chroma and lightness than Williamsburg’s Nickel Yellow. In general, genuine lead colors are toxic. As with other artists colors please refer to information from the manufacturer about the composition as well as the risks of handling these materials. The Paint List also recommends seeking the opinions of third party health and safety specialists for information about hazardous materials contained in artist paints. If you have concerns about lead, the appearance of this color can be created using Cadmium Yellow Light (PY35), Cadmium Yellow Medium (PY35), Cerulean PB35, and Titanium White PW6. Hues made with other pigments will not have the same paint film strength. Lead also has properties which make it a fast drier.
