[MUSIC] JOAN CARTAN-HANSEN: You understand the world through your five senses and your brain.

But sometimes your brain gets tricked.

Scientists have found that color can affect your appetite.

People eat less food when it's served on a red plate.

Our brain sees the color red and senses danger or a sign to stop.

But scientists have also found red food actually makes you hungrier.

Your brain associates yellow with happiness, so many restaurants have yellow flowers on their tables to encourage you to eat.

People tend to think green food is healthy, whether it is or not.

And we tend to think that white food contains no or fewer calories, which probably isn't true.

Now, blue colors tend to lower your appetite.

Research shows people don't like food that has been dyed blue, regardless of how good the food tastes.

And, Scientists say brown foods are also thought to lower your appetite because brown is associated with burnt food.

So, your sense of sight may fool your sense of taste.
