Blue is my favorite color, by far. What's yours?
I like blue too. It's between violet and green on the spectrum of light.
Haha yeah, ROYGBIV right? I feel like blue is a very popular favorite color. A lot of people I know really like the color blue.
The eye sees blue when the wavelength is between 450 and 495 nanometres.
So interesting to think about. I get kinda tripped out when I start to think about all color as just being illusions of light waves. Some animals can't even see blue, just because of how their eyes process light. Weird
The sky and the sea appear blue because of an effect called Rayleigh scattering. They aren't really blue.
Wow, really? I always thought the sky was blue because it was reflecting the ocean. At least thats what im pretty sure I learned in school lol
An optical effect called Tyndall scattering explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In the eighth century Chinese artists used cobalt blue to colour fine blue and white porcelain. In the Middle Ages, European artists used
, so that shorter wavelength violet and blue light will scatter more than the longer wavelengths (yellow and especially red light). However, the Sun, like any star, has its own spectrum and so "I" in the scattering formula above is not constant but falls away in the violet. In addition the oxygen in the Earth's atmosphere absorbs wavelengths at the edge of the ultra-violet region of the spectrum. The resulting color, which appears like a pale blue, actually is a mixture of all the scattered
