<p>Sharp cuts the chase with its bold and geometric look. It follows strict construction guidelines to convey a high-tech feel.&nbsp;The Duo style is perfect for projects that require differentiation between actions, using color to convey meaning effectively. It also allows you to customize the line thickness.&nbsp;All Sharp Duo icons are designed on a 24px grid with a 2px default stroke and two customizable colors.</p>

Sharp Duo

**Summary**: 2px line-only construction with a two-color blue system (dark blue primary + lighter blue secondary) — a structured hierarchy layer on top of Sharp's geometric precision. The cool blue palette and two-color structure read as functional differentiation, not decoration. The tone signals systematic precision: colour is used to convey meaning and category, not expression or warmth. Best for enterprise SaaS needing colour-based element differentiation, dashboard sections separating action types, and products wanting the Sharp precision language with a controlled brand colour layer.

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | 2px |
| Fill | None (line only) |
| Corner treatment | Sharp corners |
| Color | Two-color: dark blue primary + lighter blue secondary |

### Emotional Scores

Sharp Duo is one of the colder sub-styles in the catalog — the blue two-color palette is cool, and the line-only construction adds to this. It is one of the harder sub-styles in the catalog — 2px stroke with sharp corners reads as structured, not soft, with the two-color separation reinforcing this. It is one of the more formal sub-styles in the catalog — the blue colour system is corporate, reading as functional rather than warm. It is one of the more serious sub-styles in the catalog — colour is used to convey meaning and differentiation, not expression. On its human↔mechanical character, it is one of the more mechanical sub-styles in the catalog — treating icon elements as distinct functional layers in a two-color system feels systematic.

## Pairing & Compatibility

### Typography pairing

- **Primary**: IBM Plex Sans — the two-color system and corporate blue align perfectly
- **Alternative**: Neue Haas Grotesk — adds authority to the systematic color differentiation
- **Body**: IBM Plex Sans Light — creates visual breathing room inside the two-color structure
- **Avoid**: Humanist, rounded, or warm fonts — the cool-blue system requires cool-neutral type


<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>
