<p>Micro is living proof that size matters. It was built using simplified shapes to ensure legibility at the smallest possible sizes.&nbsp;The Solid style is ideal for projects where quick recognition is crucial, especially effective on dark backgrounds. All Micro Solid icons are designed on a 10px grid using filled shapes.</p>

Micro Solid

**Summary**: Micro's active-state and dark-mode sub-style — opaque fills on simplified 10px silhouettes providing maximum legibility at minimum size, purpose-built for dark UI and selected states. Simplified opaque silhouettes read as systematic components where no design decision serves expression. The tone signals unmissable utility: "we are unmissable, even when we are tiny." Best for dark UI navigation chrome, system-level contexts (menubar, system tray, notification indicators), selected states in dense data products, and any context where recognition speed at 10–16px matters more than visual refinement.

## Fit & Recommendation

### Primary use cases

- Dark UI navigation chrome where maximum legibility at small sizes is required
- System-level contexts: OS-adjacent UI, menubar icons, system tray, notification indicators
- Tab bars in mobile apps where 10–12px icons appear in constrained inactive states
- Toggle switches, checkboxes, and selection indicators at smallest permissible size
- High-density data products where every pixel of layout space has been allocated
- Contexts where recognition speed matters more than visual refinement

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | None |
| Fill | Opaque fill with transparent cutouts — background visible through cutout areas |
| Corner treatment | Simplified rounded silhouettes — internal detail is minimal by design |
| Color | Monochrome |

### Emotional Scores

Micro Solid is somewhat cold — opaque black fills with simplified silhouettes carry no warmth cues in shape or construction. It is one of the harder sub-styles in the catalog — solid opaque fills are visually hard and the simplified construction reinforces this with no soft detail to moderate fill weight. It is one of the more formal sub-styles in the catalog — the purpose is maximum contrast at minimum size, placing it firmly in a functional rather than expressive register. It is one of the more serious sub-styles in the catalog — no design decision serves expression; every one serves legibility. On its human↔mechanical character, it is one of the more mechanical sub-styles in the catalog — simplified opaque silhouettes read as systematic components, and the stripped construction removes any trace of craft expression.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Inter Medium — additional weight complements solid fill visual mass at small sizes; prevents icon from overpowering adjacent label text
- **Alternative**: IBM Plex Sans — for dark UI contexts where Micro Solid is deployed as high-contrast navigation chrome
- **Dark UI**: Inter SemiBold on dark surfaces — keeps type weight visually proportional to bold solid icon fills
- **Avoid**: Light-weight fonts at small sizes alongside Solid fills — the weight imbalance makes labels disappear while icons remain visible
