Why is the GitHub contribution graph blue? Is it because of winter?

CodePudding user response：

seems like there are different colors for the contribution graph. And each time a different color pattern is enabled. Currently it is set to variations of --color-calendar-winter-graph. There are other color patterns like --color-calendar-halloween-graph as well. github contribution graph styles

It could be because December 21st is the Winter Solstice, the shortest day of the year and the official first day of winter. Hence the cold icy blue color.
