🟥 · Symbols › Shapes · Emoji 12.0 (2019)
🟥 is a plain red square, one of the nine colored squares added with Emoji 12.0 in 2019.
Its biggest use is as a pixel: people build emoji art, pixel hearts, flags and progress bars out of colored squares, and red is the go-to for hearts and apples. On its own it reads as stop, error or alert, like a red light on a dashboard.
Paint with 🟥 in the emoji art editor, or turn any photo into emojis with the image to emoji converter.
