<p>Sharp cuts the chase with its bold and geometric look. It follows strict construction guidelines to convey a high-tech feel.&nbsp;The Flat style is easy to integrate into projects that need icons with a more illustrative purpose, working best at larger sizes. All Sharp Flat icons are designed on a 24px grid with two customizable colors.</p>

**Summary**: Solid flat fills in a two-tone blue tonal palette (dark blue + light blue) with no stroke — a diagrammatic, illustrative Sharp sub-style. Flat geometric fills without strokes read as schematic and diagrammatic, closer to technical illustration than expressive design. The tone signals structured explanation: "we diagram, we don't decorate." Best for onboarding flows, feature explainers, help center documentation, and marketing sections at 32px+ where icons carry visual weight but geometric consistency is still required.

## Fit & Recommendation

### Primary use cases

- Product illustrations and feature explainer graphics
- Onboarding flows where icons are larger and more illustrative
- Marketing sections requiring icons with color weight but geometric consistency
- Documentation visuals and help center content
- Works best at 32px+ where flat fills read as intentional, not impoverished

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | None |
| Fill | Solid flat fills, two-tone |
| Corner treatment | Sharp geometric silhouettes |
| Color | Two-color: dark blue + light blue tonal |

### Emotional Scores

Sharp Flat is somewhat cold — the blue tonal palette is cool, with dark blue and light blue reading as calm and controlled. It is somewhat hard — no stroke means silhouette edges define hardness, with sharp silhouettes on flat fill compounding the effect. It is near neutral on friendliness leaning slightly formal — the two-tone blue is neutral-formal while the flat fills introduce slight approachability. It is somewhat serious — flat fills at geometric shapes still read as task-oriented and structured. On its human↔mechanical character, it is one of the more mechanical sub-styles in the catalog — flat geometric fills read as diagrammatic, closer to technical illustration than organic expression.

## Pairing & Compatibility

### Typography pairing

- **Primary**: IBM Plex Sans — diagrammatic flat fills and structured type share the same visual register
- **Alternative**: DM Sans — slightly warmer, appropriate if the flat style is being used in illustrative contexts
- **Body**: Inter Regular — neutral, scales well alongside flat icon illustrations
- **Avoid**: Display-weight or decorative fonts — Flat is illustrative but not expressive


<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>
