How do theme colours of the social media affect the user experience?

Color exerts enormous influence on our attitudes and emotions. When the eyes are a color, they communicate with a region of the brain called the hypothalamus, which in turn sends a cascade of signals the pituitary, on the endocrine system, and then to the thyroid gland. The thyroid glands signal the release of hormones that cause fluctuations in mood, emotion, and the resulting behavior.
