Second, birds can see colors in the ultraviolet range beyond the rainbow we see because many species possess a fourth type of color receptor.
We share the other three color receptors with birds: red, yellow and blue.
What colors can birds see?
In our eyes, we have three types of colour receptors, or cones – they are sensitive to red, blue and green frequencies of light. Birds have a fourth receptor that varies across species in the type of frequency it can detect.
Are birds color blind?
A new study, published this month in the journal Behavioral Ecology, finds that birds not only can see more colors than they have in their plumage, because of additional color cones in their retina that are sensitive to ultraviolet range, but they also see colors that are invisible to humans.

What colors can’t humans see?
Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously. The limitation results from the way we perceive color in the first place.
