Aurora Borealis

Auroras, more gorgeous than rainbows, more dreamlike than lightning, more lasting than meteors.

In the very cold, inaccessible places, sunlight may not be seen for months or even half a year, and days are as dark and dead as nights. Suddenly the sky would flash with blue-green light, illuminating the whole sky and the snow-covered land. To capture the characteristics of the aurora. I simulated the color of the sky and the aurora, the contrast of their brightness relationship, and their spatial relationship.
