COLOR VISION MECHANISMS
colors theory color appearance depends on the relative red-green and blue-yellow valences Cone contrast The contrast (or relative change in quantal or energy catch) presented to each cone photoreceptor: ΔL/L ΔM/M and ΔS/S Cone contrast space A color space where the position along each axis represents the contrast of one cone class |

Trichromatic Theory of Color Vision
Large variability across individuals! But doesn’t have (strong) effects on color space color blindness About 8 of male population 0 5 of female population has some form of color vision deficiency: Color blindness Mostly due to missing M or L cones (sex-linked; both cones coded on the X chromosome) |
What is Thomas Young's theory of color vision?
• Thomas Young was the main pioneer to publicly hypothesize that color vision came about due to intrinsic properties of the human retina. Hesternely believed that there are three kinds of nerves which, when stimulated, would produce sensations of red, green, and blue.
What is the purpose of the color theory presentation?
This presentation is designed to introduce your students to color theory, which will help them make color choices that are more than appeals to aesthetics. The nineteen slides presented here are designed to aid the facilitator in an interactive presentation of color theory.
What are the features of colour vision?
Features Of Colour Vision Colour vision is a function of cones. (seen better in photopic vision) Our eyes perceive colour with wavelength of light ranging from 400 to 700nm. Below 400nm is below violet wavelength called ultra violet rays. Above 720nm is infrared and beyond visibility. 5.
What is the first stage of color vision?
The first stage of color vision is now well understood (see Chap. 10). When presented in the same context under photopic conditions, pairs of lights that produce the same excitations in the long-, middle-, and short-wavelength-sensitive (L-, M-, and S-) cones match each other exactly in appear- ance.
