1911 Encyclopædia Britannica/Palette
PALETTE (the Fr. diminutive of pale, spade, blade of an oar, from Lat. pala, spade, baker's shovel or peel; cf. pandere, to spread), a term applied to many objects which are flat and thin, and specifically to a thin tablet made of v/ood, porcelain, or other material on which artists place their colours. The term is also used of the shallow box, with partitions for the different coloured tesserae, used by mosaic workers. By transference the colours which an individual artist employs are known as his " palette." The " palette-knife " is a thin flexible knife used for arranging the colours on the palette, &c., and also for the application of colour on the canvas in large masses.
