The Earth's surface also plays a role in scattering and reflecting this light. As a result of this increased amount of scattering, the dominance of blue light is decreased and so we see an increased amount of white light.

So one might say that the sun is blue-green! As you are probably already aware, people have three color cone receptors. The three cones detect different wavelengths of light and those three different wavelengths correspond to red, blue-green, and blue. When you mix red and green light together your eye sees yellow. This is called additive color. Blue is the hardest color to see as more light energy is required for a full response from blue-violet cones, compared to green or red. Ugly has never looked quite so good.
Blue light also reaches deeper into the eye, causing damage to the retina. In fact, Blue light can be so detrimental to the eyes, that several medical studies, including a study by Molecular Vision in , have found that it can lead to macular and retinal degenerations.

Ben Davis May 31, Why on a clear sunny day sky appears blue? What is the color of the sky on a sunny day? The light striking the atmosphere outside the path of totality gets scattered in all directions, which is why the sky is still visibly blue in most places.
But near the horizon, that light that gets scattered in all directions is very likely to get scattered again before it reaches your eyes. The red light is the most likely wavelength of light to get through, eventually surpassing the more-efficiently-scattered blue light.
Rayleigh scattering affects blue light more severely than red, but of the visible wavelengths, It's only due to the sensitivity of our eyes that the sky appears blue and not violet. So with all that said, you probably have one more question: if the shorter-wavelength light is scattered more efficiently, why doesn't the sky appear violet?
Indeed, there actually is a greater amount of violet light coming from the atmosphere than blue light, but there's also a mix of the other colors as well. Because your eyes have three types of cones for detecting color in them, along with the monochromatic rods, it's the signals from all four that need to get interpreted by your brain when it comes to assigning a color.
The light response of the human eye, normalized, in terms of the three types of cones and dashed Each type of cone, plus the rods, are sensitive to light of different wavelengths, but all of them get stimulated to some degree by the sky. Our eyes respond more strongly to blue, cyan, and green wavelengths of light than they do to violet. Even though there's more violet light, it isn't enough to overcome the strong blue signal our brains deliver.
The gravitational pull on the gases in our atmosphere cause a substantial surface pressure, giving Image credit:. If we could see into the ultraviolet very efficiently, the sky would likely appear more violet and ultraviolet; if we only had two types of cones like dogs , we could see the blue sky during the day, but not the reds, oranges, and yellows of sunset.
But don't be fooled: when you look at the Earth from space, it's blue, too, but the atmosphere has nothing to do with it! This is a BETA experience. You may opt-out by clicking here. More From Forbes. Jul 23, , am EDT. Jul 15, , am EDT. Jul 8, , am EDT. Jul 1, , am EDT. Jul 20, , am EDT.
