Can colors affect your mood? Your productivity? Your appetite? The research says yes! Here are some of the most popular colors and what they mean:

Yellow

• Yellow is the color of the sun, so it reminds us of joy, happiness and cheerfulness.
• You see fast food restaurants use yellow a lot.

Green

• Green is the color of nature. It refreshes us and symbolizes harmony, healing and money.
• They say green is the easiest on the eyes, so it’s great to make your computer desktop green.

White

• White represents innocence, purity, and perfection.
• It is also seen as safe and sterile, so it’s a color used in hospitals as well.

Black

• Black represents power, elegance, formality and mystery. If you want to be taken seriously wear this color, but all black could be taken as too mysterious.

Brown

• -The color of stability, brown is also seen as masculine. If you’re a woman in a predominantly male workplace, wearing a chocolate brown suit can give you credibility.

Choosing the color of your office, your clothes or your desktop should not be taken lightly -- colors do affect our moods and productivity. However, colors are not the only thing that affects us -- one can still be efficient in a grey suit or workout well in a black outfit. But, when given the choice, picking a color that will work with you, and not against you can only help.
