But how is it with the savage tribes? Here we find, indeed, that for the painting of their bodies, as well as for other ornaments, the warm colours are almost exclusively chosen. Besides black and white, hardly any other colours than red and yellow are found at all. “The Australian has always, in his bag of kangaroo skin, a supply of white clay and of red and yellow ochre. For ordinary occasions he contents himself with dabs on cheeks, shoulders, and breast; on holidays he paints his whole body.”[125] Bushmen rub their faces and hair with red ochre; red is the Fire Islander’s favourite. Other savages use, with deep blue-black, a blazing vermilion, a combination which imparts to their faces the wildest and most forbidding expression. Among the famous discoveries which Fraas has described so well[126] was a lump of kneaded paste about as big as a nut, compounded of iron rust and reindeer fat, and intensely red in colour. Probably every huntsman of the Ice period had one of these to colour his body with. The same colours are chosen for their other ornaments as well. The Australians stripe their girdles and neck and brow bands with red, white, and yellow, and the same or similar colours are in demand with the Bushmen and Fire Islanders. Among the Botoku red feathers, as the most costly decoration, form the insignia of rank. Others wear yellow feathers in the hair, and the same ornament floats above the brow of the Australian hunter. The cool colours are scarcely ever seen in primitive ornamentation, even in combination with red and yellow. Blue decorations are extremely rare, and the Eskimo’s lip wedge of green nephrite is quite unique in colour.[127] From this brief survey we reach the conclusion that primitive man is not so sensitive as we are to the stimulus of the colder colours. In the painting of the body and some other ornamentation the prevalence of red and yellow may be partly attributed to the more general distribution of these pigments, but such a reason can not be assigned in the case of feathers, and we can not therefore deny the probability that for the savage simple green and blue lack the charm which they possess for the cultivated eye.[128] That the cooler colours are imperfectly perceived, however, is an unwarranted supposition in the provisional stage which our knowledge of the subject has up to the present time attained.[129] With them, as with children, probably the cooler colours fail to arrest their attention and excite their interest as they do ours. Whether this is the result of a kind of colour blindness or whether it is due solely to the intensive emotional effect of the warm colours it is difficult to say. The extraordinary want of susceptibility to reflected colour displayed by educated adults proves that the lack of æsthetic interest may assume the form of partial colour blindness. There are thousands, for example, who have never noticed the intense blue of a shaded cement road under a clear
