I recently get a new room painted, and it seem to be kind of too murky. I have a extra gallon. The paint is Benjamin moore pearl finished paint. Can I mix this paint beside a white semi gloss paint to sort it lighter?
Or should I just buy a lighter color adjectives together?
Thank you.
Answers:    hey as long as they are both latex paint mix away!!!!
I'd say simply buy a lighter shade. No telling if the 2 paints are compatable lacking additional background.
It is easier to make a paint dark but very tricky trying to gross it lighter.
