The color wheel is probably one of those things that you learned about as a young child and haven’t thought of since. However, to really understand color, you may have to dust off some of that knowledge.Simply put, the color wheel provides a visual representation of which colors blend nicely together. It removes all the guesswork, essentially. 

You may have heard colors described as having a temperature. A dining room may be decked out in warm tones while your friend may have chosen a cool color to finish off her bedroom. These temperatures also describe where the color falls on the color wheel.Reds, oranges, and yellows are often described as warm colors. They are typically more vibrant and seem to bring a sense of liveliness and intimacy to a space. In contrast, blues purples, and most greens are the cool colors. They can be used to calm down a room and bring a relaxed feel.When choosing color temperature for a space, you should also consider the size. Using a warm color in a tight room could make things feel a little claustrophobic. However, using cool colors in a spacious room could leave things feeling stark.

Hence, picking a color and revolving nice matches around it and adding one contrast will be a safe place to start with.
