Why sky can change color

This morning I got a very beautiful phenomenon, I got a view of orange and purple morning sky, I was very amazed by view this morning, it was very magical. I immediately took a picture with my old cell phone camera, not very good but enough to be evidence for you to see.

I took three photos in one minute, so photo I included was taken in same minute at 05.13 am. But what I'm amazed at is why the color of sky is different, while I was taking pictures in same minute.

First picture, I took a picture with cellphone position perpendicular to road in front of me, so you can see orange sky and people walking in front of me. They were walking home from worshiping at mosque. Watch starlight to match next image!

Second picture, I took a picture with cellphone tilted about 30 degrees towards sky, actually target of my photo was moonlight and starlight because in first photo I only got starlight photos. Just look at color of the sky! Very different from first picture. I think color is more similar to purple, and pay attention to moonlight and starlight! Still in same position, right?

Third picture, because I was curious about phenomenon of sky changing color when I took a photo, so I took a few steps back and took a photo with cellphone position like first photo. By picking up moonlight and starlight targets, but sky returns to an orange color. While walking home I thought it looks like my cellphone lens is broken, ha ha ha.

When I got home I took time to read some articles about causes of sky's changing color

I came to conclusion that color of sky is caused by rays of sun reaching earth. Sunlight has several types of colors, namely Red, Orange, Yellow, Green, Blue, Indigo and Purple.

Light emitted by sun to earth is blocked by earth's atmosphere and color of sun's light will be scattered by particles in earth's atmosphere. Color of sky that we see is color of sunlight that reaches earth and point of view of our vision also affects color of sky that we will see.

That is reason why sky often changes color, be it in morning, afternoon or evening. Weather conditions and earth's atmosphere greatly affect color of sky. Because, particles in atmosphere such as nitrogen, oxygen, etc. will scatter sunlight towards earth.

My curiosity has been cured, that's scientific explanation why sky can change color. I also posted this issue at https://noise.cash/post/qzmrq60t6rqj

Hopefully it can add insight to me and you. Thank you for reading till end!
