Better to be a human?

You can not only see better, but also discuss the differences?

So a dog can't drive a car because he can't see the traffic light colours.

Dogs would also have great difficulty translating electrostatic potential maps.
Just kidding; that's pretty cool.

Yo listen up heres a story about a little guy that lives in a blue world.
And all day and all night and everything he sees is jsut blue like him inside and outside.

Its very interesting, how did they figure it out?

Exactly what I want to know!

Actually I doubt we know how the dog "sees" the world, but finding out if it is capable of recognizing colors should be a matter of rather simple tests (say, try to teach it tricks that require recognizing color of an object, if it can't recognize the color, it won't be able to learn). Plus, there should be possible leads in the microanatomy of the eye and biochemistry of the photopsins present in the eye.

Good idea. Yes, by exhaustive tests with pairs of colors knowing which ones it cannot distinguish ought to tell us something.

Maybe the large swathe of brown represents these cannot-distinguish combinations.
