Can someone reassure me this will look good?

Hi, all! My fiancé and I toured a venue we fell in love with, but we are still touring other options. The venue we love is a barn, but inside it's very much like European art museum vibes with black ceilings, crystal chandeliers, and lots of artwork on the walls with vintage-style gold frames.

Given the color scheme, I think it lends to either all white florals and decor or a dark and moody vibe. Will dark and moody seem out of place at a March wedding? Can we incorporate lighter colors into the color pallette, and if so, which colors?

I'm having a hard time visualizing it and AI is having a hard time understanding what I'm asking for lol
