Choosing a color scheme or color palette is vitally important for any room. Try to determine all of the major colors you will be working with first.
When you choose your palette first, it will be easier to pull it together and you'll stay focused. You'll probably make fewer mistakes as well.
Color can visually stretch or shrink a room . For instance, if your kitchen is huge and you want to make it more cozy; paint it a warm brick red or a dark, forest green. Those colors will make the room appear smaller. However, if you're working on a small guest bath, paint the walls a light, pale, cool blue. This will help make it feel larger and also bring a calm feeling into the room.
Colors can also elicit an emotional response:
Green = soothing
Yellow = uplifting and energetic
Red = passion and daring
Soft Pink = sweet and delicate (often used in hospitals)
Blue = calming and quiet
Orange = warm and cozy
Purple = sexy or spiritual
Color can be a fun and inexpensive way to give any room an updated or completely different feel.
