Decoration tips

hey, I have bought the attached linkDining table and also the sideboard. I wanted to paint the walls a dark earthy green, however the chair covers are a teal colour. 

The house is Victorian, high ceilings, two walls are floor to ceiling white book shelves and the floor is a dark wood. 

I am struggling to decide on a wall colour, please help
