Lead Tin II

This is the warmer (yellow-oranger) of the lead-tin yellows. Type II has a deeper, warmer yellow note. Bear in mind that this is a different not only from Lead Tin Yellow Type I, but also the other lead yellow, which is genuine Naples Yellow PY41. Neither variety of Lead Tin Yellow (Type I nor Type II) has a pigment code.

In other words, there are three related pigments which can sort of blur together a bit, but they are distinct. Lead Tin Yellow type I, Lead Tin Yellow type II, and Genuine Naples Yellow which is also a lead yellow, also known by the code PY41. To complicate things further, there is sometimes some lack of distinction between Lead-Tin Yellow Type II, which has no pigment code but has C.I. number 77629, and PY46 (sometimes called massicot or litharge, C.I. number 77577). All of these are toxic.

These colors are somewhat heavy in physical weight and unobtrusive in the way they mix. In terms of color behavior, they are lower chroma than most synthetics, more mellow than most cadmiums, and have a semi-transparency to them. However they are poisonous and expensive.
