I am helping a neighbor with their master bedroom decor and the walls are this completely saturated turquoise. The color is heading towards navy but has tons of green to it.
They have hardwood floors and white plantation shutters also.
I am going to suggest a richly colored rug and white curtains with a trim on the leading edge.
I have even started a Pinterest board for them to help visualize my suggestions.
How would you work with this wall color?
