The color-matching functions for lambda greater than or equal to 540 nm: incompatibility with the blue fundamental.
The question of the blue fundamental contribution to foveal color matches for lambda greater than or equal to 540 nm is examined. It is shown that, with two almost universally accepted assumptions, such a blue fundamental contribution leads to a contradiction with the observed color-matching functions. It is concluded that the blue fundamental does not contribute to foveal color matches for lambda greater than or equal to 540 nm.
