<p>Cyber features only straight lines and sharp angles for a futuristic, high-tech aesthetic. The Line variant maintains geometric clarity.</p>

Cyber Line

**Summary**: The defining Cyber sub-style — 1px dark navy stroke, straight-line-only construction with zero Bézier curves, producing a diagrammatic schematic quality unlike any other icon set. Every path segment being a straight line communicates absolute discipline and machine-drawn precision. The tone signals technical drawing: "we are a technical drawing; accuracy is our purpose." Best for primary navigation in technology-forward products where the schematic-drawing quality reinforces brand identity — cybersecurity dashboards, AI and developer tools, financial technology with a data-authority visual language, and sci-fi or gaming-adjacent product UIs.

## Fit & Recommendation

### Primary use cases

- Primary navigation and UI controls in technology-forward products where the diagrammatic quality reinforces brand identity
- Cybersecurity dashboards and security operations products
- Developer tools where the schematic-drawing quality signals precision
- Financial technology products with a data-authority visual language
- Sci-fi, gaming-adjacent, or futuristic consumer products
- Documentation and technical content where diagram-like quality is appropriate

## Brand & Cultural Identity

### What it communicates

> "We are a technical drawing. Accuracy is our purpose."

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | 1px |
| Fill | None |
| Corner treatment | Sharp — all path segments are straight lines; no curves exist anywhere |
| Color | Dark navy blue default (customizable) |

### Emotional Scores

Cyber Line is the coldest sub-style in the entire catalog — the dark navy strokes combined with zero-curve straight-line construction produce one of the coldest visual combinations possible in icon design. It is one of the harder sub-styles in the catalog — the strict straight-line construction pushes toward hardness, though the 1px weight prevents maximum hardness. It is among the most formal sub-styles in the catalog — diagrammatic schematic-quality icons communicate technical formality and the navy colour reinforces authority over approachability. It is among the most serious sub-styles in the catalog — the strict construction rule of no curves communicates absolute discipline and seriousness of purpose. It is the most mechanical sub-style in the entire catalog — every path segment is a straight line with no organic deviation whatsoever, reading as machine-drawn at every junction.

## Pairing & Compatibility

### Typography pairing

- **Primary**: IBM Plex Sans — engineering culture alignment is direct; strong legibility in dark navy at all weights
- **Alternative**: Space Grotesk — geometric personality, slight technical character, holds in navy
- **Monospace option**: IBM Plex Mono — for developer tool and data engineering contexts
- **Display**: Barlow Condensed — condensed geometric, reads cleanly alongside straight-line icons in dense layouts
- **Body**: IBM Plex Sans Regular
- **Avoid**: Nunito, Poppins, Inter — humanist warmth contradicts cold mechanical precision


<p>Cyber is one of our most challenging icon sets: no curves, only straight lines and sharp angles. Inspired by sci-fi aesthetics, it’s perfect for bold brands and futuristic tech.</p>
