West Ham United were sitting with their heads held high in third place during the international break and, to judge from this defeat away to Wolverhampton Wanderers, possibly in the clouds.

Reference: “The non-Riemannian nature of perceptual color space” by Roxana Bujack, Emily Teti, Jonah Miller, Elektra Caffrey and Terece L. “We might be able to think of it normally but with an added dampening or weighing function that pulls long distances in, making them shorter.
“We didn’t expect this, and we don’t know the exact geometry of this new color space yet,” Bujack said. Riemannian geometry cannot account for this effect. This is because humans perceive a big difference in color to be less than the sum you would get if you added up small differences in color that lie between two widely separated shades. In the study, which combines psychology, biology, and mathematics, Bujack and her colleagues discovered that using Riemannian geometry overestimates the perception of large color differences.
Those are the colors registered most strongly by light-detecting cones on our retinas, and - not surprisingly - the colors that blend to create all the images on your RGB computer screen. The models plot red, green, and blue in the 3D space. Later, more advanced models used Riemannian geometry. First attempts used Euclidean spaces - the familiar geometry taught in many high schools. So the research team was surprised when they discovered they were the first to uncover that the longstanding application of Riemannian geometry, which allows generalizing straight lines to curved surfaces, didn’t work.Ī precise mathematical model of perceived color space is needed to create industry standards. “Our original idea was to develop algorithms to automatically improve color maps for data visualization, to make them easier to understand and interpret,” Bujack said. Modeling human color perception enables automation of image processing, computer graphics, and visualization tasks.Ī Los Alamos team corrects math that has been used by scientists, including Nobel Prize-winning physicist Erwin Schrödinger, to describe how your eye distinguishes one color from another. That model was suggested by Bernhard Riemann and developed by Hermann von Helmholtz and Erwin Schrödinger - all giants in mathematics and physics - and proving one of them wrong is pretty much the dream of a scientist.” “Our research shows that the current mathematical model of how the eye perceives color differences is incorrect. It was published in the Proceedings of the National Academy of Sciences. Bujack is lead author of the paper on the mathematics of color perception by a Los Alamos team. “The assumed shape of color space requires a paradigm shift,” said Roxana Bujack, a computer scientist with a background in mathematics who creates scientific visualizations at Los Alamos National Laboratory. The study has the potential to boost scientific data visualizations, improve televisions, and recalibrate the textile and paint industries.
This incorrect model has been used by scientists and industry for more than 100 years. New research corrects a significant error in the 3D mathematical space developed by the Nobel Prize-winning physicist Erwin Schrödinger and others to describe how your eye distinguishes one color from another.

The research contradicts long-held assumptions and will improve a variety of practical applications of color theory. A new mathematical representation has found that the line segments representing the distance between widely separated colors don’t add up correctly using the previously accepted geometry. This visualization captures the 3D mathematical space used to map human color perception.
