Birds see a wider color spectrum than we do. Humans have three types of cones (RGB color space), and birds have at least four dimensions of color vision, taking them into the ultraviolet end of the spectrum.
Increased dimensionality produces a qualitatively different color perception, one that we cannot intuitively understand.
“The tetra- or pentachromatic color space of birds appears to be the most complex in nature and is likely involved in virtually all areas of the animals' lives, from the discrimination and recognition of objects to more complex behavioral tasks such as navigation, the classification of objects, and social and sexual behavior.” (more info)
