| **My question concerns the ability to know the time that the redness of the sunset is no longer visible in the horizon. Is there a certain degree at which the redness/yellowness/whiteness disappears? I'm aware that the whiteness disappears at 18 degrees but i'm more interested in the redness.** | **My question concerns the ability to know the time that the redness of the sunset is no longer visible in the horizon.

| To the best of my knowledge/understanding, there is no well defined angle at which these colors/light will disappear. In general the last light from the horizon would be red since it has to go through so much atmosphere and it would just fade to black. I don't think that there would be a specific angle, since that would depend on the amount of dust and particles in the air you're looking through which changes from place to place. | To the best of my knowledge/understanding, there is no well defined angle at which these colors/light will disappear.
