Abstract
THE author states that his object has been to supply the long-felt want of a power of recovering a given colour sensation and of a colour nomenclature by which that sensation may be quantitatively described. To this end “scales of red, yellow and blue were constructed of glass slips, trie slips of each scale being all of one colour with a regular variation in intensity from 0.01 to 20 units, equal units of the three scales being in colour equivalence with each other. The test of equivalence is that a white light viewed through equal units of the three scales should give no evidence of colour. … The fogs on Salisbury Plain furnished the light actually used.” It was found that red, yellow, and blue were the only colours suitable for systematic work, and that any colour could be produced by their combination. The dimensions of the unit are, it is said, necessarily arbitrary, but the scale-divisions are equal, while the unit itself is recoverable.
