This scattering refers to the scattering of electromagnetic radiation of which light is a form by particles of a much smaller wavelength. These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue. Your blood is actually red. The blue hue of your veins has more to do with how your eyes absorb and see color than the color of the blood itself.
The level of oxygen in your blood cells determines the brightness of the red color. Blood pumped directly from the heart is oxygen rich and bright red.
The surface of the planet Mars appears reddish from a distance because of rusty dust suspended in the atmosphere. From close up, it looks more of a butterscotch, and other common surface colors include golden, brown, tan, and greenish, depending on minerals.

Take a look at light through a prism and notice all the different colors that you can see.
Light that looks white to our eyes actually is made up of many different colors. Each color can be thought of as a light wave with a different wavelength or size. Within the small range of wavelengths or colors that we can see with our eyes, the shorter waves are blue and the longer ones are red. Colors such as green, yellow, and orange lie in between the blue and red ends of the visible spectrum. If you multiply. Early scholars thought that Earth was the center of the cosmos because as they peered into the night sky everything seemed to move about the Earth.
In the 16th century, Copernicus pointed out that Earth orbited around the sun it was helio-centric and spun on an axis. Though the Earth is spinning, we do not feel it.
If you've ever flown on a large plane, it is hard to tell that you are moving. However in the case of the plane or the Earth, if it stopped suddenly we would feel that.
Since we are rotating with the Earth at a constant rate, the rotation is not felt. Scientists think that this abrupt change was caused by loss of ice mass at the poles. Why does a sunrise sky have its orange-reddish color? To answer this question, we have to define "scattering. This is called scattering. The two most common to meteorological processes are Rayleigh scattering particle is small relative to the wavelength of light and Mie scattering spherical particle is about the same size as the wavelenth scattering.
When the sun is low on the horizon during sunrises and sunsets, the sunlight travels through more of the atmosphere. Shorter wavelength colors blues and violets get scattered out. This leaves more of the longer wavelength colors like yellow, orange, and red. This is why sunrises often take on such colors.
When the sun is higher in the sky, smaller particles Rayleigh scatter much of the blue wavelength, which is why the sky appears blue.
The human eye is more sensitive to blue than violet otherwise our characteristic blue sky might be violet. Doesn't dust or pollution brighten the colors? The notion that dust and air pollution brighten sunrises and sunsets is a myth. Daytime happens when we have twirled to face the Sun directly — so its sunbeams travel very fast directly to us. So we know why the sky is bright during the day and dark at night. In fact, all things are made of molecules, including you and me.
But each molecule is much, much smaller than a grain of sand. The molecules then begin to play with the light — bouncing it back and forth between themselves. Blue light has a shorter wavelength than red or pink light. This means it can only bounce between the molecules for a shorter distance.
