Rublev makes a series of genuine Lead-Tin Yellows, and the Dark variety is still still pretty light in value. For context, all of the lead-tin yellow varieties are lighter in value than the Naples yellow genuine varieties made by Rublev. The Lead-Tin Yellow Dark is warmer / oranger than the lead-tin yellow (regular). The photos online make it difficult to discern the hue, and it is possible that it varies from batch to batch. The Lead-tin yellow dark is a warm pale gold, where the regular lead-tin yellow is closer to a true yellow hue. There is a slight ochre or orangy note in the dark variety. Please note that 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. It goes beyond the scope of the site to comment on the toxicity of every paint, however some paints stand out. The Paint List also recommends seeking the opinions of third party health and safety specialists for information about hazardous materials contained in all of one’s artist paints. If one is concerned about the lead, the appearance of this color can be created using PY42 yellow ochre, PB28 Cerulean Blue, Cadmium Yellow Light PY35, and Titanium White, though hues will not have the same paint film strength. Lead is also a drier.
