This is the bedding for my north facing room

I would stick with a white that leans cool (blue), just like the photo!

any suggestions for a cool blue white?

Choose sheets, throws, throw pillows, curtains, and art first. Try to find a multicolored item that you love, and pull a wall color from that. Yellows look beautiful with blue, I’d consider something in the family of beach sand.

This is the bedding I already purchased for my guest bedroom.
