Is the calligraphy blue?

Generally speaking, it is not good to use blue as the background color of calligraphy, so it is rare. This is because most calligraphers' pen and ink are black, and the background color is blue, which gives people the impression that they are vain, neither beautiful nor prominent, and it is difficult to show the charm of calligraphy. Therefore, it is not good to use blue as the background color of calligraphy!
