I think that picture is edited, white are not a color i have seen, most often the general color are green, but reddish and blue colors can also occur, the color are determined by the gasses in the atmosphere.

The colors most often associated with the
aurora borealis are pink, green, yellow, blue, violet, and occasionally orange and white. Typically, when the particles collide with oxygen, yellow and green are produced. Interactions with nitrogen produce red, violet, and occasionally blue colors.
The type of collision also makes a difference to the colors that appear in the sky: atomic nitrogen causes blue displays, while molecular nitrogen results in purple. The colors are also affected by altitude. The green lights typically in areas appear up to 150 miles (241 km) high, red above 150 miles; blue usually appears at up to 60 miles (96.5 km); and purple and violet above 60 miles.
These lights may manifest as a static band of light, or, when the
solar flares are particularly strong, as a dancing curtain of ever-changing color.
The sun just had a major tantrum i hear.
