Great idea! Thanks!

How about a red throw over one of the pouf? Then put something red like your rug in the throw pillows along with some blue?

I just wanted to say that you really scored on that rug. It’s beautiful.

I think the poufs are fine with the rug but not in that location. Looks like you're trying to use them as a coffee table with trays? Try them in several other places. In front of the long plant stand for a start.

That’s exactly what I’m using them as, haha—didn’t know that wasn’t ok!

Of course it's okay. Find some pillows that have both red and blue in them to tie the furniture in with the poufs and your beautiful rug and also wall art that you really like with those colors in them, perhaps over the couch, for a cohesive and warmer scheme. You need to repeat the rug colors in other pieces and that shouldn't be difficult since your seating furniture is neutral. It's a lovely sun room.
