Paint the trim of the doors and windows with a light-colored latex paint in semi-gloss. Choose white or ivory. Dark wood trim can close in doors and windows.
Paint the surrounding wall a few shades darker than the trim. This provides a visual depth of field and makes the trim on the doors and windows stand out.
Paint the door a light color with semi-gloss latex paint. Use the same shade as the trim, or go a shade or two darker.
Install curtain rod or blind brackets, using a cordless screwdriver, two inches out from the sides of the window trim. This will add an extra four inches of visual space around the window trim.
Hang horizontal window blinds or drapes with a horizontal stripe. These draw the eye to the width of the stripe and makes the window seem wider.
