I have picked up you sample colors. In attempting to select a color I noticed that if I was in a different room with different lighting, the color appeared different. With this info, I went to the store & requested a quart of the color. The clerk told me that they couldn't mix the color for that small of an amount. It's one of your designer colors. I really didn't want to buy a gallon and not like it.
I have heard from numerous persons that they wished the paint companies would be able to supply them with a small container of the paint colors they selected. Something like a magic maker (Magic Paint Brush???)
I believe sales would improve if this became possible. Seeing is believing.
