I have an issue I hope someone can help me with. A while back I painted my den orange. I got a stain on one of the walls and decided to crack open the same can of paint I used when I first painted the room since I had some left over. I painted over the stain and also touched up a few other areas. The next day I was surprised/annoyed to discover that instead of being orange the paint had dried to more of a brown color. I thought that maybe the paint had gone bad since the lid wasn't on that tightly so I went and bought some fresh paint and used the code off the lid of the original paint can to match my paint. The new paint matched exactly to the small dab of paint on the old can that the store puts on top of each can they mix up. The weird part is that the new paint is also too dark. I'm really confused. I used this exact same color for all of the other walls so I don't understand why it's so dark compared to the rest of the walls when I try to touch something up. I'm using Colorplace semi-gloss. Each wall had one coat of primer followed by 2 coats of orange paint. Is there some way of lightening up the paint myself until it matches what is already on the wall?

I thought I'd get some opinions before if decide to do this... I live in florida in a older block home with terrazzo floors. My plan is to install 3/4" hardwood flooring thoughout the house. Details include following a procedure to lay a 6mil vapor barrier directly over the floor and fasten a 3/4" subfloor on top using 1 3/4" tapcons spaced 8" along the perimeter and 12" in the center. The 3/4" oak will be fastened directly over the 4 x 8 sheets of subfloor. That said, would it be of any additional benefit if I painted the terrazzo floors to act as a moisture barrier before I add the poly? It is my primary resistance and I expect to stay in my home for a very long time. I don't mind spending the extra $$ if it will provide some additional benefit. Thanks!
