Do you think light or darker turquoise would look better with brown?

i'm painting my room and i want to paint two walls turquoise and the other two chocolate brown. but i can't decide what shade of turquoise i want to use. i've narrowed it down to a turquoise thats called "cool and clear turquoise" and a light turquoise shade called "shimmering summer pool". i can't decide if a light turquoise would look better with brown or if the more traditional turquoise would look better. please tell me what you think would look better, thanks! :)
