Why Does Your Skin Look Green?

The video explores the phenomenon where recently shaved individuals exhibit a greenish-blue tint on their skin. This is more noticeable in fair-skinned people and is linked to visual perception similar to Pointillism, where the brain blends small dots into a cohesive image. Two explanations are provided: one relates to the visual blending of stubble and skin color, and the other involves light absorption and reflection by hair. The effect is influenced by lighting and is less visible on darker skin tones.
