50 shades of grey

We are redecorating our bedroom and painting it grey with a highlight wall of yellow. So yesterday my hubby and I went on a little adventure to Home Depot. And its beyond overwhelming how many shades of grey and yellow there is.

Cement Grey
Real Grey
Earthy Grey
Elephant Ear

Sunshine Yellow
Sunflower
buttercup
butterscotch

And about a hundred more colors....

$50 of paint, and 3 hours of wandering around the store later I am hoping we are happy with our choice of Cement grey and Sunflower yellow. I don't want my room to look like a parking garage though. But its just a name right? Whats in a name?
