blue square
Cerulean four-sided shape
A blue square is a shape with four equal sides and right angles, colored blue.
In skiing and trail systems, a blue square marks intermediate-difficulty runs—harder than green circles, easier than black diamonds.
On social media, posting a blue square may signal solidarity with a cause, following the pattern of awareness campaigns using colored shapes.
