Dogs are red-green colour-blind, like many humans. They can see other colours.
The so called forbidden colours are green/red and yellow/blue. The light frequencies automatically cancel each other out
We see different colours because other colours are being absorbed.
Different species have different needs from their vision and may well see (Infra red/Ultraviolet etc?) and other totally different light frequencies from humans. They may also see some colours vividly and other colours as shadows, so their vision works differently from ours because different things are important to them. No doubt they will see whatever colours they need to see for their survival in their natural habitat.
probably
Quote from the related link: "Butterflies can see red, green, and yellow, but they also see color in the ultraviolet range, which reveals patterns on flowers-and other butterflies-that we can't see."
yes they do see in colour but not in the same way as we do they see in darker colours
You have receptors for three primary colours in your retina. You can perceive the thousands of colours due to stimulation of the these receptors at different intensity in various permutations and combinations.
cones are deactivated while rods are activated. As cones are responsible for seeing colours, we cannot see colours in the dark due to the deactivation.
Rabbits are colourblind and do not see the same colours that we do. Rats can see blues and greens but not red at all. Black eyed rats can see one third of the humans can while red eyed rats can see only one thrid of what a black eyes rat sees.
Same as humans
animals see just the same way as us. but they see different colours. some only see in black and white.
