Transmitted light is made up of a of colors. The longest wavelengths of light are on the red end of the spectrum and the shortest wavelengths are on the blue/violet end of the spectrum. When sunlight enters our atmosphere it crashes into oxygen and nitrogen. The color with the shorter wavelength is spread more by this crash. Because violet and blue are the shortest of the wavelengths the sky appears to be violet / blue. But your eyes are more sensitive to blue light than they are violet light, so we see the sky as blue.
cats and dogs
The phrase is supposed to have originated in England in the 17th century when city streets were filthy and heavy rain would occasionally carry along dead animals.
The idea that seeing dead cats and dogs floating by in storms would cause people to coin this phrase is just about believable. People may not have actually thought the animals had come from the sky, but might have made up the phrase to suit the occasion.
A KCALB is a rare breed. If you see one, it's considered good luck. If you feed one after dark, it will multiply.
