History Folklore

<p>Bold style features strong, solid shapes for instant recognition. It gives excellent legibility on dark backgrounds.</p>

**Summary**: Solid opaque fills with transparent cutouts and rounded outer silhouettes, monochrome — the highest-weight Ultimate sub-style. Notably harder and more serious than its line-weight siblings despite sharing the same rounded geometry. The tone signals confidence and directness: solid visual weight that reads as active, selected, or primary without requiring colour. Best for active states, mobile tab bars, badges, dark-mode-first products, and any context requiring maximum legibility at 12–16px; best used as the emphasis layer alongside Regular rather than as the sole icon weight.

## Visual & Technical Specs

| Corner treatment | Rounded outer silhouettes |
| Color | Monochrome |

### Emotional Scores

Ultimate Bold is near neutral on warmth leaning slightly cold — solid black fills are high-contrast and authoritative; not cold, but not warm. It is among the hardest sub-styles in the catalog — solid shapes represent the highest visual weight in the family and are unmistakably hard. It is somewhat formal — heavy fills read as authoritative and direct, with rounded silhouettes preventing full formality. It is one of the more serious sub-styles in the catalog — strong graphic weight signals seriousness with no decorative elements. On its human↔mechanical character, it is somewhat mechanical — rounded outer shapes retain some human quality while the density of fill reads as systematic.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Archivo Black / Space Grotesk Bold — matches the visual weight of solid icons
- **Display**: Syne, Clash Display — adds graphic boldness in marketing contexts
- **Body**: Inter Regular — provides contrast between the heavy icon and light body text
- **Avoid**: Ultra-thin or hairline fonts — the visual weight imbalance is extreme and reads as unresolved
