The reason dogs can only see certain colors is because of the photoreceptors in their eyes. Both dogs and humans have rods and cones in their eyes, but humans have more cones, while dogs have more rods. Also, humans have three types of cones, but dogs only have two types.

Money For Nothing lyrics
I want my, I want my M.T.V.
Now look at them yo-yo's, that's the way you do it
You play the guitar on the M.T.V.
That ain't working, that's the way you do it
Money for nothing and your chicks for free
Now that ain't working, that's the way you do it
Let me tell you them guys ain't dumb
Maybe get a blister on your little finger
Maybe get a blister on your thumb
We got to install microwave ovens
Custom kitchen deliveries
We got to move these refrigerators
We got to move these colour T.V.'s
The little faggot with the earring and the makeup
Yeah buddy, that's his own hair
That little faggot got his own jet airplane
That little faggot he's a millionaire
We got to install microwave ovens
Custom kitchen deliveries
We got to move these refrigerators
We got to move these colour T.V.'s
We got to install microwave ovens
Custom kitchen deliveries
We got to move these refrigerators
We got to move these colour T.V.'s
Look at that, look at that
I should have learned to play the guitar
