Kids Find Free Coloring Books and Printables TO COLOR

A great way for kids to learn about the world around them through color.



Scientists have found a woman whose eyes have a whole new type of colour receptor She sees 99 million colours more than the rest of us.

Why do we see the colors we do?

Some of it goes back to the types of color-absorbing pigments that we inherited from bacteria more than a billion years ago. The specific colors we see are, in part, an artifact of bacterial needs. These ancient color-sensing pigments are tuned to two different wavelengths - shorter ones that correspond to blue and longer ones that go with yellows or reds.



A tiny group of WOMEN can see 'invisible' colors that no-one else can perceive.
H uman tetrachromacy is a color perception potential arising from the inheritance of X-chromosome-linked human color vision photopigment opsin genes. Since women have two X chromosomes, they could potentially carry two different versions of the gene, each encoding for a cone that is sensitive to slightly different parts of the spectrum. In addition to the other two, unaffected cones, they would therefore have four in total - making them a “tetrachromat”.

Scientists call these people tetrachromats, meaning “four colours”, after the four - rather than three - colour photoreceptors they possess. Birds and reptiles are tetrachromatic, and this is what allows them to see into the infrared and ultraviolet spectra. Human tetrachromats cannot see beyond the normal visible light spectrum, but instead have an extra photoreceptor that is most sensitive to colour in the scale between red and green, making them more sensitive to all colours within the normal human range. Tetrachromats are believed to see 100 million colors as opposed to the 1 million seen by "normal" people. Antico has her own gallery in San Diego, California, where she uses her enhanced vision to create vibrant paintings bursting with color.

The woman with superhuman sight: Scientists say they have found doctor who can see 99 MILLION more colours than average human.

seeing color can be traced back to genetic mutations

From the inside of our heads, it feels as if colors are intrinsic aspects of the outside world and our eyes are beautifully designed to see them. But we humans are merely sampling the possible ways of sensing the spectrum of light. Most of us see more colors than dogs, but miss millions of colors that make up the world for birds, reptiles, and insects.
