👉 Tachornism is a phenomenon in which an object appears to have different colors or textures based on its position and orientation relative to a stationary observer. It occurs when light passing through a material at two different speeds results in a phase shift, causing the color of the light to appear different depending on the angle it passes through. This effect is observed in various forms such as butterflies, flowers, and leaves that change color or texture under the influence of their surroundings.
