I need guidance inpicking a blue color that goes well with brown

I really like lighter shades of blue and aqua with brown and darker blues such as navy or royal with beiges.

my personal favorite...Turquoise. It’s such a lovely blue green and goes with just about everything.

tiffany blue (like the color of a Tiffany's Jewelry box. It compliments brown really well and it looks classy and expensive. Brown can look outdated easily, but by pairing it with Tiffany Blue, it looks modern and fresh.

Go to your local paint store and bring home paint samples of the color blues that appeal to you. Hold them next to your brown to see which blue best fits your style and the color you desire.
