The old saying of keeping your walls white to increase space is a myth! There are no rules when it comes to selecting the colors for your space. Start by planning your color placement on your walls first. Lighter colors opposing light sources (windows) and/or darker walls visually open up an environment. Keep your palette choices to sharper more saturated colors. Dull colors, even when in lighter shades, can diminish the liveliness of an area. If your apartment happens to have a hallway or walkway painting it a darker color than the room it leads into can make the room appear bigger.
