Room is 10 ft x 12 ft, couch is red, carpet is dark green, room has 1 window and a sliding glass door. My husband wants to go dark but I’m not sure. What would be best?
It depends on the room use and your own preferences. If the room will be used as a theater, watching movies, then dark colors would be best. But if it is for general purpose use then some lighter colors might work better, better light reflection.
A good compromise is to use a darker color as an accent and a main lighter color (2-3 shades lighter). You could also use a darker color for one wall and the lower third of the other walls with a lighter color for the top 3 walls, add chair rail trim to separate the colors.
Remember the ceiling is typically a lighter color and this is the largest area of any room. Just having a lighter complementary colored ceiling will dramatically lighten up a room.
