Should Marigolds Blossom in the Bedroom?

Here is a snapshot of our latest creation. Last night we finished this bedroom off with a bright yellow wall. In theory it sounded like a good idea. Dark grey and dark yellow go great together. In fact, it really does look pretty awesome. But here's my concern...this is going to be our bedroom. Do we really want an insanely bright wall? Or would we be better off with all grey, so that the bedroom is dark, cozy, and mellow? I'm thinking the latter, but that means we have to paint over the Marigold Blossom which means yet another night of work, and another day further away from moving furniture in.

What do you think? Should we keep the Marigold or paint over it with more grey??
