笑脸符号

Harvey Ball于1963年创作的黄色圆形笑脸图标，是现代面部表情符号设计的灵感来源。

The smiley face — a yellow circle with two dot eyes and a curved mouth — was designed by Harvey Ball in 1963 for an insurance company's employee morale campaign. It became a cultural icon of the 1970s and beyond.

When emoji were first designed for mobile phones, the smiley face was the natural template for face emoji. The yellow skin tone used for default emoji is a direct reference to the classic smiley.

Today, "smiley" is sometimes used colloquially to refer to any face emoji, though strictly it refers to the classic 🙂 or 😊 designs.
