EXPERIMENT XII.
IT is worth observing, that, tho Painters can imitate most Colours which are to be met in Nature, yet they make use of no more than, White, Black, Red, Blew and Yellow, to produce all their Compositions: Thus Black and White represent several sorts of Grays: Blew and Yel∣low, Greens; Red and Yellow, Orange Tawny; Red with a little White, a Carnation; Red with an Eye of Blew, a Purple; and by a Decom∣position of all these, they represent what Co∣lours they please. But in producing of Colours it is to be observ'd, that we must take care that the Pigments be so harmless as not to destroy each others Textures, for then the success will be frustrated.
