Moths are often dull in color as a form of camouflage, helping them blend into their natural environments, such as tree bark or leaves, to avoid predators. Their muted tones provide better protection during the day when they are resting. This adaptation enhances their survival chances, as less vibrant colors make them less noticeable to birds and other predators.
