I like both! I'd try the darker if I didn't mind painting. :)

White works, but we voted for the bolder, darker color. Lovely space.

The blue is an awesome choice

I like the darker color! It really makes all the other white pieces in the room stand out.

Beautiful choice to paint! Adds that pop! Good luck!

I am with IdaClaire--- I thought that a dark wall with that sofa would be overkill but it's so so nicely done! Yup it works.

@Vision Interiors - For the purpose of this simulation I just used straight black on the Benjamin Moore Personal Color Viewer, where it produces the dark gray-blue you see here. If I pick an actual dark gray-blue, in comes out looking way lighter on the Color Viewer.

The darker color works very nicely and provides a great backdrop for your artwork.
