P.O.38 is broad in scope. The list of applications includes special media, such as wax crayons, artists colors, and wood stains, including those that are solvent based. The products are very lightfast (step 7 on the Blue Scale) and fast to overcoating. Blends of P.O.38 with yellow pigments, such as P.Y.83 or P.Y.120, or with carbon black produce useful shades of brown. 

Apart from these areas of application, P.V.32 is also used in solvent-based wood stains. The lightfastness of the products equals step 6 on the Blue Scale, which is very good. These systems may safely be overcoated. Pigment blends with yellow pigments, such as with P.Y.83, and blends with black provide interesting shades of brown. 

Rape seeds are small, round (0.1-0.2mm diam.) and can be yellow, brown or black. The oil content usually lies within the range of 40-60%. The oil can be obtained either by expelling or solvent extraction or a combination of the two. The crude oil is dark amber in colour and contains a high level of phos-phatides (3.5%), pigments, especially chlorophyll from unripe seeds, and sulphur compounds (Crawford, 1982 Mag, 1983).
