Principle of lizard discoloration:

There are three kinds of pigment cells under the skin of chameleon: green, blue and gray. Green and blue pigment cells are long spindle shaped, widely distributed in subcutaneous tissue and perpendicular to the skin surface; The gray pigment cells are located under the green and blue pigment cells and are distributed parallel to the skin surface.

The principle of chameleon color change lies in the change of the position of green and blue pigment cells. When the middle part of green pigment cells expands, the skin surface will show more green; When the blue pigment cells expand in the middle, the skin shows more blue; When the green and blue pigment cells shrink, the skin loses its green and blue color, revealing the gray pigment cells at the bottom of the skin.
