Yellow is the color of sunshine. It’s bright, warm and happy. Yellow can make you feel energetic and optimistic, but it’s also a warning color that can make you nervous or distrustful.

Taste is one of the five senses, along with touch, smell, sight and hearing. Taste refers to our ability to detect sweet, sour, bitter and salty flavors in food and beverages through receptors in our mouths.

The taste buds on your tongue are sensitive to salty, sweet and sour flavors. Your sense of taste helps you decide whether food is good enough to eat or not. It also helps you enjoy eating more because it makes food more appealing than it would be otherwise.

How Does Taste Work?

A chemical called tastant enters your mouth through your taste buds when you eat something with a detectable flavor — like chocolate or an apple — and combines with a specific receptor (salty, bitter or sweet) on the surface of the taste bud cells in your mouth. The combination causes an electrical signal to travel from the taste bud cell through nerve fibers in your tongue to areas of your brain that recognize sensory information such as texture and temperature (taste).
