It's not uncommon to see red sunsets or yellow ones. I live in the mountains but have lived in the Great Plains, Hawaii, the Pacific Coast, and 3 different Mountain ranges. The sunsets change color depending on weather and geographic location. I've seen red, orange, yellow, and even violet sunsets. The sunset in post #6 is like a sunset that is almost night like right before the sky starts turning black. The sunset in post #9 would be like a gal on a California beach looking west over the pacific and it's not quite dusk- I'd guess early evening around 6-7 pm?
