Rounded Fill - Streamline Material

**Summary**: Streamline Material's warmer active-state sub-style — opaque fills on more generously rounded 24px-grid silhouettes, the complement to Rounded Line for navigation hierarchy in consumer-facing Material products. Generous rounding retains warmth even at solid fill weight, making this warmer than Outlined Fill at equivalent visual mass. The tone signals approachable emphasis: "we are warm and direct when needed." Best for active and selected states in consumer-facing interfaces using Rounded Line for inactive states, feature highlights where filled silhouettes should read friendlier than the Outlined Fill equivalent, and mobile navigation tab bars in consumer apps.

### Emotional Scores

Material Rounded Fill is somewhat warm — more rounded silhouettes retain warmth even at solid fill weight. It is somewhat soft — filled weight increases hardness while generous rounding offsets this, landing near neutral leaning soft. It is somewhat friendly — rounded filled shapes read as welcoming, slightly warmer than Outlined Fill. It is near neutral on playfulness — fill weight and rounded shape balance each other at the midpoint. On its human↔mechanical character, it is somewhat human-feeling — rounded filled silhouettes have an organic quality that prevents a mechanical reading.
