Emotion Icons: Happy, Sad, Surprised, and Neutral Face Symbols #3459671 (License: Personal Use)

This image displays four universally recognized yellow emoji-style faces arranged in a 2x2 grid, each conveying a distinct basic emotion: happiness with a wide smile, sadness with a curved frown, surprise with wide eyes and an open oval mouth, and neutrality with a flat line mouth. The minimalist black-and-yellow design ensures high visibility and cross-cultural interpretability, making it ideal for educational, psychological, or interface contexts.

Commonly used in websites about emotional intelligence, mental health resources, UX/UI design libraries, or educational materials teaching facial expression recognition; matches user intent to quickly identify or illustrate fundamental emotions.
