What kind of colors can dogs see?

Dogs see the world in a different way than we do. They are dichromats, meaning they have two types of cone cells in their eyes, compared to our three. This means they see a limited range of colors, primarily shades of blue, yellow, and gray.

Here's a breakdown:

* Blues and greens: Dogs can see blues and greens, but they may not distinguish between the two as well as humans.

* Yellows and oranges: Dogs can see yellows and oranges, but they may perceive them as more muted.

* Reds and purples: Dogs struggle to see red and purple, which appear more gray to them.

Think of it like this: Dogs see the world in a kind of muted, sepia-toned version of our world.

While they may not see the full spectrum of colors we do, dogs are still able to distinguish between different objects and environments based on brightness, contrast, and shape. They rely heavily on their sense of smell to navigate their world and understand what's around them.
