After the whole “Fifty Shades of Grey” thing, I’m sure plenty of couples painted their walls RED, just like the ones in the book’s PLEASURE DUNGEON.

Well, here’s why you shouldn’t take advice from poorly written books cause a new survey found that people who have red walls in their bedroom have the LEAST SEX of anyone!   People whose walls are painted a caramel color have the most sex!

The survey also found a few less sexy results of other paint colors . . .

1.  People with blue walls sleep the best.

2.  People with purple walls are the most likely to have insomnia.

3.  And people with gray walls are the most likely to do online shopping in bed.
