A really beautiful yellow, primrose is very apt. It was made for those warm highlights whether in still life, landscapes or portraits. This is so often imitated as a 'hue' and so much is lost, it has vast potential as a very light glaze, to lift certain areas of a painting. It also would have a place on a lot of palettes as a contrast to a warm, red tendency, cadmium yellow.
It is a lead chromate/lead sulfate, obtained synthetically as a yellow crystalline powder by precipitation from a solution of a lead salt. Chrome yellow primrose has good hiding power with bright yellow hue and average tinting strength.
Chrome was discovered by the French chemist Nicolas Louis Vauquelin in late 1790 in the mineral crocoite (lead sulfochromate). Vauquelin studied the different chrome compounds and found he could obtain a wide range of colours from greenish-yellow to orange shades. A synthetic lead chromate (mainly chrome yellows) manufacturing process was published in 1809, although they were not mass produced until 1820 when the first large chrome deposits were discovered in North America.
