Dogs see in black and white
Myth busted
Dogs can see colors. In experiments, dogs distinguished blue and yellow visual cues, even when brightness cues changed.

The bit that matters
- Dogs have two types of color-sensitive cone cells; typical human color vision uses three.
- Having two cone types does not mean dogs see only two colors. Their exact subjective view is not shown by this experiment.
