In the Bible, (Matthew XVI: 2-3,) Jesus said, “When in evening, ye say, it will be fair weather: For the sky is red. And in the morning, it will be foul weather today; for the sky is red and lowering.”
Pink sky means clouds (I.e. Moisture). Clouds in the west (pink at night) are generally moving away from you, clouds in the east (pink in the morning) are moving towards you.
“Those are the kind of storms that may produce hail and tornadoes.” Green does indicate that the cloud is extremely tall, and since thunderclouds are the tallest clouds, green is a warning sign that large hail or a tornado may be present.
The disk of the Sun appears mostly white, with a slight bluish tinge. This has nothing to do with clouds or ice, but by the Martian dust that permeates throughout the planet's atmosphere. The dust in the atmosphere, like dust in a sandstorm here on Earth, absorbs blue light, which gives the sky a primarily red color.
Most thunderstorms occur in the late afternoon. By this time of day, the sun is beginning to set. The orange hue is caused by the same process that causes the vivid colors at sunsets. Shorter wavelengths of light (blue) are scattered quickly, leaving only the yellow-orange-red end of the spectrum.
When sunlight travels through the sky, it passes through evaporated water and gas and clouds and other particles in the air. These particles both refract and reflect the light, scattering some of sunlight's colors. In turn, the morning sunlight fills the sky with a blaze of pinks and reds.
Why you might be seeing red when you look at the sun
When particles, such as smoke or dust, fill the atmosphere, the longer wavelengths of light — which look red — scatter more effectively. On Wednesday, the wind is continuing to be from the northwest, and that brings with it some residual smoke, White said.Indeed, there is scientific validity to the adage, "red sky at night sailors delight; red sky in the morning sailors take warning." This saying has very old roots. In the bible (Matthew 16:2-3), the following quote is attributed to Jesus: "When it is evening, ye say, fair weather: for the heaven is red.
When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.
The beautiful colors from a sunset are caused by the atmosphere. As the sun gets lower and lower in the sky, its light passes through more and more air layers—compared to noontime, when the sun is directly overhead. And those layers are filled with dust and water particles.
Contrary to popular belief, pollution in the lower atmosphere does not make great sunsets. In fact, haze and other large particles in the air mute the colors of the sky rather than enhance them. In polluted areas you'll be more likely to see greyish pink skies rather than crisp oranges and reds.

Why is sunset more reddish than sunrise? The light from the Sun travels through Earth's atmosphere it undergoes scattering before it reaches us. Thus, there is more probability for shorter wavelength light to get more scattered than for the longer wavelength light.
Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. Also, the surface of Earth has reflected and scattered the light.
Bohren explains that as the sun falls lower in the sky, the spectrum of direct sunlight is shifted from blue toward a perceived red, yellow and orange. “When this setting light is transmitted by a massively thick cloud composed of water droplets and ice particles, the results are a green sky,” said Bohren.
The sun's light pours outward to illuminate every portion of our solar system so that the space around the sun is almost entirely flooded with light. But there are dark places. These are in the shadows of planets, moons and other objects in orbit around the sun. And it's these shadows that create night.
The stars twinkle in the night sky because of the effects of our atmosphere. When starlight enters our atmosphere it is affected by winds in the atmosphere and by areas with different temperatures and densities. This causes the light from the star to twinkle when seen from the ground.
The reddish coloration arises because sunlight reaching the Moon must pass through a long and dense layer of Earth's atmosphere, where it is scattered.
The smaller the wavelength of the light the more the light is scattered by the particles in the atmosphere. Thus, the light with the higher wavelengths pass through the atmosphere with little or no scattering, while blue and violet waves are more scattered.
Our sky is actually purple
Purple light has higher energy, and gets scattered more than blue. The predominant blue and purple scattered light triggers not only the blue cones in the eye, but also a little of the red and green cones.Our sky looks blue because the shorter wavelengths on the spectrum, the blue, hit air particles and molecules and bounce around, spreading out and becoming visible as they do so. The spectrum of light was spread so the the violet wavelengths filtered through all of the moisture and turned our skies to purple.
