When you see blue on a lizard, it is not necessarily a sign of blue pigment. Like the blue sky and blue eyes, it may be a sign of no pigment at all. This type of blue is caused by Rayleigh scattering of light from small particles, which may be colourless. The probability of scattering is inversely proportional to the fourth power of the wavelength, strongly favouring blue over red. If the particles are too big, the colour becomes grey or white.
Unlike the eyes of snakes, those of lizards are not covered by scales, but the lizard can blink, which no snake can do. |
