Pig Emotion Icons - Red, Yellow, Green Facial Expressions for UX & Education #2316044 (License: Personal Use)

This vector-style illustration features three stylized pig heads stacked vertically, each rendered in a distinct color to represent an emotional state: red with downturned mouth for sadness, yellow with straight line mouth for neutrality, and green with smiling mouth for happiness. The clean, flat design uses soft pastel inner ears and consistent eye styling to maintain visual harmony while clearly differentiating sentiment.

Commonly used in educational apps for children, mental health dashboards, user feedback interfaces, or gamified progress trackers where intuitive, non-verbal emotional cues are needed. Matches user intent for quick visual communication of mood or system status.
