The base of your ring conducts heat, transferring your body’s temperature to the liquid crystals inside. The crystals twist and move in response, and as their wavelengths change with the heat, their color changes. [3] X Research source When your body temperature is stable, the crystals stay in a neutral state and project a blue or green color. As your temperature rises, the crystals compress into shorter wavelengths and appear purple in color. Thermotropic crystals are also used in watches, calculators, and computer screens to display images.
Your body temperature can also be affected by the environment and your activity levels. Are you someplace cold? Have you been exercising? Mood rings can’t predict complex emotions, complicated feelings, or subtle mood shifts, as one simple color can’t describe everything you’re experiencing. Even if a mood ring isn’t always right, they’re still super fun to use and wear!
