Detect colour

The color of light coming from an object is what gives it color. Light travels into the eye to the retina located on the back of the eye. The retina is covered with millions of light sensitive cells called rods and cones. When these cells detect light, they send signals to the brain. Cone cells help detect colors.

There are about 120 million of them in our eyes - compared to around 6 million cone cells, which are the cells that detect colour. So, in other words, our eyes have the potential to be highly sensitive to light, but they're usually so stimulated that we haven't really been able to test their limits.How to use the colour match tool.
