After more than 25 years of searching, neuroscientists in the UK recently announced that they've discovered a woman who has an extra type of cone cell - the receptor cells that detect colour - in her eyes.

Coloured freeze-fracture scanning electron micrograph (SEM) of the layers of the retina, the light-sensitive tissue that lines the inside of the eye. Rod and cone cells (green cylindrical objects, upper frame) form the outer layer of the retina. The highly-sensitive rods respond to dim light, while the cones detect red, blue and green light.

What is Color Universal Design?   		  People see color with significant variations. In Japan, there are more than 5 million people in total who see color differently from ordinary people, due to their genetic types or eye diseases. Color Universal Design is a user-oriented design system, which has been developed in consideration of people with various types of color vision, to allow information to be accurately conveyed to as many individuals as possible.

A high-magnification view of the human retina. Rod cells (assist in light perception) are in red, while cone cells (assist in color perception) are in green. Each cell’s DNA is in blue.

White is a color, the perception of which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in equal amounts and with high brightness compared to the surroundings. A white visual stimulation will be void of hue and grayness. White is the lightest possible color.

Scanning Electron Micrograph of the Human retina. The back of your eye is packed with rod cells (in grey), which are sensitive to brightness, and cone cells (in color) which are sensitive to color. Each cone cell is specific for either red, green, or blue respectively. Those who are color blind most often cannot tell red from green because the genes for red and green pigment are very close to each other on the X-chromosome. Since males only have one X chromosome males most likely express…

Finding a Blue Cone in a Sea of Green:  The retina uses different types of cones cells to detect individual colors.  Here is a picture of six cone cells that detect blue light (colored green) surrounded by a sea of cone cells that detect green light (colored red and blue).  Courtesy of Wei Li Laboratory, NEI.

[Image Source] FLASHBACK  This is a zebrafish retina (eye) that is stained with an antibody that recognizes double cone cells (photoreceptors).  It has also been stained with other things to recognize different layers, which is what gives you the colors you see above.  When antibodies are used for staining, this is known as immunohistochemistry (immuno- referring to the immune reaction that creates an antibody and histo- referring to the tissue being stained).  Antibodies are made by…

Guiding Light | The Scientist Magazine® SPLIT SPECTRUM: When a rainbow of white light enters the retina, funnel-shape Müller cells guide the beam through layers of cells and cellular processes to the photoreceptors (rods and cones). Müller cells function as optical fibers, directing and concentrating the yellow-green spectrum of light, to which many cone cells are tuned to respond maximally. Blue light seeps out of the Müller cells to activate rods.
