In Tromsø, most of the Northern Lights outbreaks are green. Large displays can give other colours, depending on the outbreak's distance to the earth.
Most outbreaks of the Northern Lights are green, but once and a while we can see tinges of pink or white around the edges. An even rarer occurrence is violet in the centre. The Northern Lights can sometimes have blue-green tinges or on other occasions the colour is closer to a mixture of green and yellow. Red Northern Lights are extremely rare. However, this does occur when the Northern Lights break out at a higher or lower height than normal.
