Kat, that Benjamin Moore site lets you change the colors on a photo of the rooms, so you can experiment with how combinations look.

Select any sample room, and then you can change the colors

I have one wall in my living room that has a bay window in it
that is painted yellow, neither pale nor bright, and the drapes
on the bay window are yellow. But, all the other colors are
natural, hardwood floor, wood walls, brick fireplace.

Yellow goes a long way. Think about maybe one wall being yellow.
