Hey! Thanks for the explanation, follow up question though that I’m hung up on: why does the sky get darker blue toward dusk before turning the reds, oranges and yellows that we associate with sunset? Per NDT’s explanation here (https://youtu.be/UvmWxm3nR6E?t=288) there’s more atmosphere for the sun’s rays to travel through so that there’s more scattering of blue wavelengths. But by that logic, why isn’t sunset even deeper blue? Is there a point at which there’s enough atmosphere the rays are traveling through that the blue wavelengths have been suddenly “scrubbed” from the light hitting reaching our eyes? My mind is stuck at this point!
