You might have heard and even asked that question many times just for having a conversational icebreaker.
If you think about it, color is a big part of our lives. It's one of the first concepts that mothers teach their children. What child is not fascinated by color, from glittering coins, crayon coloring to puddle rainbows?

Don't you love to feast your eyes on the rich tones of flowers or the brilliant shades of sunset?

But color doesn't affect only your eyes and how you see or what you see. (In fact, your skin absorbs much more color than your eyes ever do.) Though you may never have realized this, color can heal your body and make you feel good. Color can raise or lower your blood pressure, activate or suppress your appetite and make you feel energetic or sluggish.

Color is a communicator. All over the world, red means stop and green means go. Bright yellow airport signs are easy for people to notice. Green garbage cans in city parks blend into the environment. Stores, restaurants, offices, hospitals and other public places often take color into account when planning wall painting and decor. They will choose their colors - whether it's pale green for a hospital or orange for a restaurant - depending on how they want their customers to react. (Pale green is soothing while orange activates the appetite.)

Colors have power. They affect your life in many more ways than you would ever think.

Just look at your everyday language, and you will see how we all unconsciously connect color with emotion. Are you feeling blue, seeing red or growing green with envy? Are you in a black mood, or are you observing the world through rose-colored glasses? Ever thought about the color name of baby pink and baby blue? Simply, they're the colors used most often for nurseries.

You may not know this, but all these color expressions have physiological explanations. Yes. Really.

Feeling blue? That's not surprising. Blue has a calming effect on the brain (read on to see how that works), and if you're in slow mode it can make you depressed. On the other hand, red is a stimulating color that brings out emotions and passion in people and can provoke anger. No wonder you may "see red" sometimes. Why green for envy? Well, it has been shown throughout the centuries that different negative emotions are stored in different organs. The liver is where envy goes. And the liver stores bile, which is green.

The list goes on and on.

Bet you didn't know that color is also essential to your diet. Modern medical wisdom, specifically the National Cancer Institute, now says it is not enough to just "eat your greens." In fact, you should be sampling the entire color spectrum every day.

Why? Well, ongoing research shows that the bright colors in fruits and vegetables are important for you because they come from the phytochemicals inside them. Once you eat a fruit or vegetable, these protective substances pass into your body along with their protective benefits, affecting even your cell structure and DNA!

Each color is important because it means a different range of health benefits for your body. Which is why, you should be thinking color when you do your fruit and vegetable shopping
