I like this medium for painting, and as you can see, it doesn't darken any more than any good oil mix.
Or any less! All oil yellows.
This test had no drier, the yellowing is because of the oil. 2013, 18 years later it was the same color
as stand oil, sun dried and raw oils. This oil was heated to sponificate the white lead.
NEXT, #7 OIL YELLOW
PREVIOUS, #5 Oil Yellow
