Apparently, scientists have proven that dogs can see colour, but not as many shades as we do and not with the same intensity. When dogs see a rainbow, therefore, they likely just see far fainter colours than we do. But when they see a fogbow, like this one spotted over Oxner’s Beach, Riverport, Nova Scotia, Canada by Michael Peters (Member 42,102), they likely see something very similar to us.

Fogbows form when the tiny water droplets in fog refract and reflect the sunlight, separating the visible light into its constituent wavelengths. Because the water droplets are so small, the effect of diffraction spreads the colours to the point that they mix back together to appear almost as white light again. Finally, an atmospheric optical phenomenon that dogs and people can enjoy equally.
