<p>Core is timeless, like the Helvetica font or The Beatles. With its minimalist design and neutrality, it can adapt to any layout.&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 Core Duo icons are designed on a 14px grid with a 1px default stroke and two customizable colors.</p>

Core Duo

**Summary**: Core's two-color system — 1px rounded line with dark periwinkle blue primary and lighter blue secondary, providing colour-based hierarchy in enterprise SaaS and productivity products without full multi-color commitment. The periwinkle blue is softer than Sharp Duo's corporate blue, creating a polished two-tone system that reads as considered rather than cold. The tone signals semantic colour use: "we use colour to convey meaning, not emotion." Best for enterprise SaaS and productivity tools wanting a controlled two-tone icon system, documentation and help centre iconography, and dashboard systems where colour differentiates category or status.

## Visual & Technical Specs

### Visual properties

|----------|-------|
| Stroke weight | 1px |
| Fill | None (line only) |
| Corner treatment | Rounded corners |
| Color | Two-color: dark periwinkle blue + lighter blue secondary |

### Emotional Scores

Core Duo is near neutral on warmth leaning slightly cool — the periwinkle blue two-color system is cool but softer than sharp duo equivalents. It is one of the softer sub-styles in the catalog, as the 1px rounded line at the 14px grid remains light and non-aggressive despite the two-color structure. It is somewhat friendly, with the duo system reading as polished and considered rather than warm but not corporate. It is near neutral on playfulness leaning slightly serious — colour differentiation communicates function and hierarchy. On its human↔mechanical character, it is somewhat human-feeling — the two-color system adds systematic quality while rounded geometry retains a human register.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Inter — the blue duo system and humanist neutral type share the same functional design values
- **Alternative**: IBM Plex Sans — slightly more structured, appropriate for the slightly formal dual-colour system
- **Body**: Source Sans Pro — clean, readable, supports the two-colour icon structure
- **Avoid**: Serif fonts at body weight, warm rounded display fonts


<p>The Helvetica of icons. Core is stripped to essential form with generous spacing. It's a timeless workhorse for interface design.</p>
