What to do with unsatisfying paint colour?

[某某]

We bought two can of paints from Home Depot.
Used one can up in a room.
But at night, we find the color is a bit lighter than we have imagined under the light and didn't like it. What can we do?
Can we go back to Home Depot and ask them to put more of one color into the paint?

I'd try my luck with Home Depot first. We had the same problem with our kitchen, the paint was much lighter than we had thought, but after a little while we got used to it.

Oh well.
