Dogs and colors

Dogs are believed to be generally color blind, although they are able to see some color.. The reason for this is that humans have three types of color receptors in the eye that can detect the colors blue, red and greenish yellow, whereas dogs only have color receptors for greenish blue and yellow.

This means that dogs are not completely color blind but they are unable to see the complete spectrum of colors that humans do. It is believed that dogs are unable to differentiate between red, orange, yellow and green, and that they have the same problem with blue and grey. Studies however claim that dogs can tell the difference between blue and yellow.
