<p>Sharp combines pure geometry and bold structure for a brutalist, high-tech feel. The Solid variant provides filled geometric shapes for maximum impact.</p>

**Summary**: Maximum-weight Sharp sub-style — opaque fills with transparent cutouts, sharp geometric silhouettes, monochrome. Solid fills and sharp cutouts remove every expressive element to leave only function and command. The tone signals decisiveness: shapes read as components, not symbols, communicating authority without negotiation. Best for primary actions requiring instant recognition, feature highlights, badges, and active states in enterprise products where visual hierarchy must be unambiguous.

## Fit & Recommendation

### Primary use cases

- Strong hierarchy icons — primary actions that must be immediately noticed
- Feature highlights and status indicators
- Navigation tab bars in high-density apps
- Badges and labels
- Any context requiring maximum legibility at very small sizes (12–16px)

---

## Brand & Cultural Identity

### What it communicates

> "This is decisive, not negotiable."

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | None |
| Fill | Opaque fill with transparent cutouts — background visible through cutout areas |
| Corner treatment | Sharp geometric silhouettes |
| Color | Monochrome |

### Emotional Scores

Sharp Solid is among the coldest sub-styles in the catalog — solid black fills with sharp geometric silhouettes leave no warmth cues anywhere. It is the hardest sub-style in the entire catalog — maximum visual weight with filled geometric shapes at 0° corners represents the hardest possible form. It is among the most formal sub-styles in the catalog — high contrast and authoritative shapes communicate command and function. It is among the most serious sub-styles in the catalog — solid fills with sharp cutouts remove any expressive quality, leaving purely functional icons. On its human↔mechanical character, it is among the most mechanical sub-styles in the catalog — white cutout detail reads as mechanical precision, with shapes reading as components rather than symbols.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Archivo Black / Neue Haas Grotesk Bold — weight-matches the visual mass of solid fills
- **Alternative**: Space Grotesk Bold — assertive but not aggressive
- **Body**: IBM Plex Sans Regular — provides contrast between heavy icon and lighter body text
- **Avoid**: Light or hairline fonts — the visual weight imbalance is extreme and reads as unresolved


<p>Sharp combines pure geometry and bold structure for a brutalist, high-tech feel. It’s raw, trendy, and unapologetic. It pairs best with typefaces that have strong construction, such as Futura, Gill Sans, or Space Mono.</p>
