I think the antlers, teak coloured wood and grey tweed give masculinity here and balances out the duck egg blue. Also, I think monochrome textiles and industrial style lighting works. I'd go bolder with the accessories than what they have here tho!
DROP CLOTH by Farrow & Ball. This colour and its name is a nod to painters and decorators; a drop cloth is the traditional name for the indispensable painter’s dust sheet which this colour embodies. Nice colour for use in rental.
