<p>Nova is a cross between Streamline and Material. The Solid variant provides filled icons combining both design philosophies.</p>

Nova Solid

**Summary**: The opaque-fill sub-style of Nova — same concept-appropriate hybrid geometry expressed through filled silhouettes. Solid weight increases hardness and pushes the register toward serious compared to the Line sub-style's near-neutral scores; the hybrid concept-appropriate silhouettes moderate the hardness relative to strictly geometric solid families. The tone signals competence and clarity: familiar shapes that communicate primary action status without aggression. Best for active states and selected navigation in systems using Nova Line for inactive states, dense interfaces where 1px strokes are insufficient, and high-contrast contexts including dark-mode-primary products.

## Fit & Recommendation

### Primary use cases

- Active states and primary actions in navigation systems where Nova Line handles inactive states
- Dense interfaces where 1px strokes are insufficient for legibility
- High-contrast requirements (accessibility-focused products, dark-mode-primary)
- Feature highlight icons where solid fills provide visual hierarchy without colour
- Mobile tab bar selected states

## Brand & Cultural Identity

### What it communicates

> "We are legible to everyone, and our primary actions are unmissable."

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | None |
| Fill | Opaque fill with transparent cutouts — background visible through cutout areas |
| Corner treatment | Hybrid — same mixed-language as Nova Line, expressed through silhouette shape |
| Color | Monochrome (black) |

### Emotional Scores

Nova Solid is near neutral on warmth — opaque fills add visual weight while hybrid silhouettes retain the circle elements' warmth, with solid weight and geometric warmth balancing at neutral. It is somewhat hard — solid opaque fills increase visual hardness, though concept-appropriate silhouettes moderate this compared to strictly geometric solid families. It is somewhat formal — solid fills add authority while familiar Material-adjacent shapes remain accessible, leaning slightly formal without being austere. It is somewhat serious — solid weight communicates function while recognisable shapes communicate competence, leaning serious without being cold. On its human↔mechanical character, it is near neutral — opaque fills increase systematic quality while concept-appropriate silhouettes retain human reasoning, producing a genuine midpoint.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Inter SemiBold — weight-compatible with opaque fills; maintains the neutral professional register
- **Alternative**: Roboto Medium — Material-native pairing for the solid weight
- **Body**: Inter Regular
- **Dark UI**: Inter Medium at white — provides weight balance with white-on-dark solid icon silhouettes
- **Avoid**: Ultra-light fonts that create weight imbalance with solid fills; serif display at headline sizes unless deliberate contrast is the design intent


<p>These icons follow our Streamline’s structure and loosely adopt Google Material’s style. With no padding, they appear larger and became the predecessor to our Material Pro set.</p>
