The answer is yes, eyes can change color with mood. However, it is important to note that this change is usually very subtle and not always noticeable. The reason for this is that the human eye is made up of many different colors, all of which can be affected by changes in mood. For example, when someone is feeling happy or excited, their pupils will often dilate ( widen ) in order to take in more light. This results in the iris (the colored part of the eye) appearing darker than usual. Conversely, when someone is feeling sad or anxious, their pupils will often constrict ( get smaller ), resulting in the iris appearing lighter than normal. So while mood can definitely affect the color of your eyes, it’s important to remember that these changes are usually quite small and may not be noticeable to others.
