Blue Square
This is a square, which is blue. This emoticon can be used to represent anything blue. It is often found on traffic signs and architectural drawings. In addition, in many design drafts, designers often decorate some blue squares to create a sense of technology and business style.
Different platforms depict different square patterns. The squares depicted on most platforms have four right angles, but in the emojis on Twitter and Facebook platforms, the four corners of the squares have certain radians and look relatively smooth. In addition, the squares depicted by WhatsApp and Emojipedia platforms are gradually changing color, and the colors gradually darken from top to bottom. Microsoft and OpenMoji platforms, on the other hand, depict black edges on the square periphery, which makes them look thicker and heavier.
