What color is the sky? Please, thank you

The color of the sky is not singular, when you are in a good mood the sky is blue, and vice versa. Hehe. Satisfied.

When you are with friends, the sky is green, full of joy and carefree, When you are with your lover, the sky is pink, full of warmth and mood, When you are in a good mood, the sky is blue, clear and bright, When you are in a gloomy mood, the sky is gray and gloomy, So the color of the sky, I can't define, Who doesn't know what color the sky is, The sky is fickle and people are fickle, The color of the sky, should it? The color of the deuterium should be determined by the heart. So the sky is blue.

In my eyes, the sky is blue when I am happy; When sad, the sky is gray and gray. The heart is changing, and the sky is changing!

If you look at it with your heart, the sky is pink.

Whatever color you like, it's what color you like.

If I ask you what color the sky is, it must be blue. Is it really blue? You will say that when the air is ***, when the autumn is high and cool.

The tone of the sky is blue, including the Earth when viewed from the spaceship, and the Earth is also blue. But when we look up at the sky, it's not always blue: sometimes it's because of the season, sometimes it's because of the weather, sometimes it's because it's morning and evening.

When the wind blows in spring, the sky is gray and yellow, especially when the sandstorm is raging, the wind and sand are full of sand, and the sky is a mess. The sky seems to be cut, and sometimes you can't see the sky.

In summer, it was rainy and cloudy, and the sky was painted black, and if it was lighter, it was lead gray; Black and gray are mixed and moved, and the sky becomes an ink painting. On a sunny day, the sun shines brightly, and you dare not look at the sky, it must be white.

The autumn sky is clear and blue, and the sky appears deep and lofty; If there are white clouds, the sky should be counted as blue and white: blue sets off white, and white sets off blue.

Winter days are often iron-blue, as described in a person's face. I thought that in winter, when the sky is still white, especially after heavy snowfall, the sun and snow reflect each other, and the sky becomes white. Most of the time, due to the haze, the sky is chaotic and it is not clear what color it is.

The sun is also not clear, and it always feels like an egg yolk.

The sky is still red. One day I watched the sunrise, the sun was shining, and half of the sky was red. This brings me to the idea of the sunset, when the sun sets, a red cloud appears at the end of the sky, a soft halo.

I also thought of the rainbow, which is a seven-color rainbow, and although it appears rarely and is short-lived, it is very magical and magnificent. It is a masterpiece of nature, a masterpiece of the sky!

At night, the sky is naturally black, but at night when there is moonlight, it is not completely black. When the moon and stars are scarce, the sky is clear, as blue as the day; If it is shining, the whole canopy will be milky white.

The sky is colorful and the sky is colorful. Different colors of the sky make people's moods different: when the sky is black and gray, people's mood is either depressed or heavy; When the sky is blue, the heart is relaxed; When the sky is chaotic, the mind is restless; When the sky is red, hope rises in my heart and there is infinite yearning; When the sky highlights the rainbow, the poetry suddenly overflows, and life is so wonderful!

The so-called different colors of the sky are just the main colors, and the sky is not single in each season and at different times, and sometimes it changes rapidly. The spring breeze blows, and the sky is also blue; When the autumn rain continues, the sky is naturally black and gray. When it is clearest, there will be a black cloud; After heavy rains, rainbows often rise.

Look at the sky more, have more emotions, and make the colors of life not monotonous.

According to Rayleigh's law of scattering, short waves dominate in scattered light.

For example, if the wavelength of red light (720 nm) is a multiple of the wavelength of violet light (400 nm), the scattering intensity of violet light is about 4 times (i.e., 10 times) of red light. Therefore, the scattered light of the sun is blue-purple in the outer part of the atmosphere, and the blue component is more than the red light component in the inner layer of the atmosphere, making the sky blue.

The same color as the air. If you keep your eyes open, the sky is blue. Those who squint only see a blue line.
