I went to a paint store to get 2 separate gallons of paint. One was for my hardwood floor. The other was for the surrounding walls. It is a small room. The colors I chose was a latex flat White with a tint of pink (a blush) for the walls and ceiling. For the floor, i chose an acryllic latex White with a deeper pink tint. On the display cards, they looked like night and day. When I painted the room, both colors were nearly identical (a disaster). How can one make sure you are getting what you selected and asked for?
