Painting exterior of home. We want to use a dark colour on the windows and particularly the bars on the windows, so that they don't stand out.
If I use a dark colour on the outside of windows and use a light white colour on the inside side of the windows, will it work? and what colour would I use on the floor of the window - i mean when the window is slid up....the base or floor which is both insde and outside when window is slid up - where the two colours would meet

(wood vertical sliding windows)
