The colours of the floor, the ceiling and the walls have a
substantial optical impact on how you experience the space.
You can make a room seem larger, smaller,
wider, narrower, deeper, higher, lighter and warmer.
Color value can help define one object
in contrast to a lighter color, or help create spatial illusions.
Light colors are said to recede, so it will make your small space look more spacious, and airy. Dark colors are said to move toward you, so it will bring coziness to a very cold, large room.
Neutrals can also help bring balance to your space
Neutrals provide continuity and cohesion for the different elements in the space, blending different rooms and color schemes.
Darker neutrals defuse other colors, while lighter neutrals intensify them.
Neutral tones do not have to be just stark white.
The classic neutrals are considered to be black, white, and gray,
and are classified as the "true" neutrals; the colors that are not on the color wheel.
They are considered to be a combination of all the colors in the spectrum.
Let your walls be a canvas on which to make a statement about your personality.
