What is it about?
The scientific community generally agrees on the theory, introduced by Riemann and furthered by Helmholtz and Schroedinger, that perceived color space is not Euclidean but rather, a three-dimensional Riemannian space. We show that the principle of diminishing returns applies to human color perception. This means that large color differences cannot be derived by adding a series of small steps, and therefore, perceptual color space cannot be described by a Riemannian geometry.

Why is it important?
This finding is inconsistent with the current approaches to modeling perceptual color space. Therefore, the assumed shape of color space requires a paradigm shift. The paradigm of a Riemannian color space had been unchallenged for over 100 years.

This is soooo exciting! I had always dreamed of proving wrong someone famous ;) But this is a class of famous that I had not dared dreaming about :D
