Cone cells, which sense red, green or blue light, detect white more often than colors, researchers report September 14 in Science Advances. The textbook-rewriting discovery could change scientists’ thinking about how color vision works.
Red and green cone cells each come in two types:
One type signals “white”; another signals color,... The large number of cells that detect white (and black — the absence of white) create a high-resolution black-and-white picture of a person’s surroundings, picking out edges and fine details.
Red- and green-signaling cells fill in low-resolution color information. The process works much like filling in a coloring book or adding color to a black-and-white film, says Sabesan, who is now at the University of Washington.
Cells surrounded by cones that detect a different color were more likely to send white signals, the researchers found. That finding is unexpected and runs counter to a popular idea that cones ringed by cells detecting other colors would be better at color detection, MacLeod says." ScienceNews
So basically your eye takes a snapshot in B&W and then fills it in instantly with the colors...AMAZING DESIGN......
(You really think that "evolved" as a product of time + chance?)
Thank you for making me so wonderfully complex!
Your workmanship is marvelous—how well I know it.
