Red-Browed Amazon Parrot

This parrot is colourful in visible light.

Vision (also known as sight) is a primary sense in most animals which allows them to see light to at least some extent. Some can only tell light and dark apart, while a species of mantis shrimp are believed to have the best colour vision.


Nearly every animal in existence has sight. This appears as the background, other organisms, and/or structures, in normal colours. If an animal doesn't have any sight at all, they will have a blank screen instead, which would be replaced by an image coloured by the response of another sense, such as sound, ultraviolet or infrared sight, which helps build up surroundings.
