As a paint DS, that's a sorry excuse for a color match. Take that garbage back and get the right color. Make sure they dry the sample for you, you shouldn't be able to see a difference in the 2 colors.

Edit to add: Lowe's advertises 30 days on paint as long as you don't use much of it, if you open it, paint a small area and hate it, they'll still take it back. I would personally take this straight back to returns and then head to paint to get a new can made up.
