The same way you can’t have a number that’s both positive and negative, you can’t have a color that’s red-green or yellow-blue. These are impossible colors. A rainbow of impossible colors. There are three main types of “impossible” colors: Forbidden colors.
If a celestial object piqued your interest, you’d be sure to look at both the red- and blue-sensitive images as a first indication of the quality of light it emits. For example, extremely red objects are bright on the red image but barely visible on the blue.

There are two types of impossible colors: 1. There are colors the visual cortex of the brain constructs by mixing signals from either both eyes or different parts of one eye. Examples include bluish-yellow and reddish-green. 2. There are impossible colors the eye could see if the red, blue, and green cones could react differently in response to vis...
Hewitt D. Crane and Thomas P. Piantanida devised a test in 1983 that allowed some observers to see colors that weren’t in the CIE 1931 color spaces (mathematical relationships that linked wavelengths of light to perceived colors). The test consisted of either a vertical red stripe adjacent to a vertical green stripe, an alternating field of red and...
In 2006, Po-Jang Hsieh and his colleagues at Dartmouth College repeated the 1983 experiment, but gave participants a color map and asked them to identify the color produced by the alternating stripes. Viewers identified intermediate colors (e.g., a muddy brown for reddish green). Why were the results different? It could be the participants in the 1...
Impossible or forbidden colors aren’t the only colors the brain can see although the eye cannot produce them from the visible spectrum. For example, chimerical colorsare imaginary colors that may be seen by looking at a strong color until cone cells become fatigued and then looking away. Looking toward a white object results in an afterimage compos...
If you’re still confused or don’t understand how impossible colors work, this video shows how your eye decides between red and green or between blue and yellow. References 1. Billock, Vincent A.; Gerald A. Gleason; Brian H. Tsou (2001). “Perception of forbidden colors in retinally stabilized equiluminant images: an indication of softwired cortical ...
So, for example, a beam of strictly yellow monochromatic light excites the red and green cones, but not the blue so much, because yellow falls between red and green in the rainbow. If two beams of light, one red and one green, were mixed in your eye, the result would look yellow.
Jan 10, 2017 · The Hungarians divide red into two colors. If you speak a language with fewer color terms, you might say there are less than seven. If you speak a language without a word for “blue” for...

Jul 7, 2019 · How to See Impossible Colors. Impossible colors like reddish green or yellowish blue are trickier to see. To try to see these colors, put a yellow object and blue object right next to each other and cross your eyes so that the two objects overlap. The same procedure works for green and red.
