This is tangentially related to Terragen, and I'm just curious if anyone knows the answer.

Why does the sky for sunrises and sunsets seem different (at least where I'm located). Sunrises get more light blues, light yellows, lighter pastel type colors, but sunsets get the more vibrant and dramatic reds, purples, oranges, etc. You would think they would look the same as the whole process is similar (sun gradually becomes visible and lights up the sky). Where I'm located, sunrise if over land and sunset is over ocean so maybe that makes a difference?

Terragen doesn't make any distinction in this regard. If the sun goes down, it always looks like a sunset (to me anyway)

Perhaps because during the day, moist has evaporated (by the sun's warmth), loads of cars excrete their fumes, work kicks up dust, so the air is fuller with particles, resulting in more breakage of sun's light, hence more reds.
AI will probably know. And I think it could be done in TG, but also easily adjusted by hand.
