ColorChallenge SaturdayIndigo: Twilight

It's a lovely Saturday my Dear Steemians! Today is Saturday Indigo and I find it very challenging to look for something to present the color today. But here it is the Twilight.

Twilight is simply the time of the day between daylight and darkness; whether after sunset or before sunrise. The time when the sun is already below the horizon and its rays are scattered by the Earth's atmosphere to create the color of twilight through small particles in the atmosphere.

I'm very much amazed by the color of the sky during twilight. But, there's something I feel inside while watching the setting sun... Sadness... Why do I feel sad? Maybe because after the sunset is the darkness? What about you? What do you feel as you look at the twilight? Please let me know.
