I purchased 2/2 gallon buckets of ceiling paint. I painted the living room last weekend. This weekend I painted the connecting kitchen. I forgot to marry the paint buckets. So now two colors. What do I do now?? Short of repainting those awful "popcorn" ceilings...

I would say you are going to have to repaint the entire ceiling as I don't know of any other way to get it to match. Just remember to box all the paint needed to paint the ceiling before you start to make sure it is all the same color.

Did you mean mix all of the paint?? as in mix it all togather. I had the same paint and color. but didn't mix the 2 2gal togather. I just had the 2 rooms meet togather and they didn't match.

It is always a good idea to box or mix paint when you have more than one container as you found out even factory made colors can vary from one can to the next.
