Aurora at high latitudes typically takes on almost monochromatic shades of green. These images are from a rare event 2022-04-01 in Fairbanks, Alaska, showing an unusual amount of colors in the blue and red spectrum. The colors are not the result of shifted color balance as daylight white balance was used on the camera. While the colors were detectable by eye, the human eye is not very sensitive to colors at these low light intensities opposed to the camera sensor.
