Mood ring Color meaning meaning in English ‌

Short stories based on words:
" Information "
Mood rings can't tell you exactly your emotional state, but the crystals are calibrated to have a pleasing blue or green color at a normal resting ambient temperature of 82F (28C) for the average person. As the surrounding body temperature rises, its response to passion and happiness, the crystal twists to reflect blue. When you're excited or nervous, blood moves away from the skin and flows more to the internal organs, cooling the fingers and causing the crystals to twist in the other direction to reflect more yellow. In cold weather, or if the ring is damaged, the stone will turn dark gray or black and become unresponsive.
