The red colour of burning fire
p. 255
[paragraph continues] (agni) is the colour of the elementary fire (tegas), its white colour is the colour of water, its black colour the colour of earth,' &c. Now those three elements--fire, water, and earth--we recognise in the Svetâsvatara passage, as the words red, white, and black are common to both passages, and as these words primarily denote special colours and can be applied to the Sânkhya gunas in a secondary sense only.
