This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Red: Because it is not considered a hot planet so it cant be blue.
Orange:this is the color which we get to see from earth in late morning.
yellow: Its in the afternoon.
The sun is a star, not a planet. The sun is not quite red, it is a yellow dwarf in terms of star 'species'. The orange in late morning is from scattering of light in the atmosphere. Usually it is blue, but at certain angles, it can be viewed as other colours. Yellow is acceptable though.
Red, Orange, Yellow, Green, Blue, Indigo, Violet. This is because the sun radiates pure energy in the every form of light possible (ummm...you can argue with me here.). This includes the visible light spectrum which includes every color that the human eye can distinguish. And it's actually not true that the sky is blue. It's purple, it's just that the color purple is the hardest to see and it's so close to blue that your mind just processes it as blue.
It very well depends on the location of where you are seeing the sky and also on how you define sky itself. If by sky, you mean the visible atmosphere and everything in it, then yeah, the sky actually is purple. See, when the sun radiates the light, it scatters all the colors around. The purple is scattered most because it has such a long wavelength and this is what gives the sky it's purplish effect. It looks blue because of our eyes' inability to acknowledge purple very well. However, in the afternoons, the same scattering effect takes place but since the sun is at a slant rather than directly above, the light has to travel through many more atmospheric obstacles, and red, orange and yellow with their very short wavelength have the best chance to maneuver through these obstacles. It mostly looks like other colors if there is pollution in the area

That's kind of what I thought too. At least, it reminds me of something I saw on a tv show. Also, isn't the sky actually clear
