<p>Ultimate is the world's largest icon family. The Multicolor version brings a playful, flexible look by combining colored outlines with filled shapes.</p>

**Summary**: 1px stroke with multi-color flat fills — each icon element gets an independent color (teal, orange, green, red visible). The friendliest and most playful sub-style in the Ultimate family, sitting near the warm-playful extreme of the entire catalog. The tone signals accessibility and delight: colour variety per element reads as informal, expressive, and immediately approachable. Best for consumer-facing marketing and onboarding, app explainer graphics, feature comparison sections, and social media content on light backgrounds; avoid in dense navigation chrome where multi-colour adds cognitive load.

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | 1px |
| Fill | Multi-color flat fills — each icon element gets independent color |
| Corner treatment | Rounded |
| Color | Multi-color (teal, orange, green, red) |

### Emotional Scores

Ultimate Colors is one of the warmer sub-styles in the catalog — the multi-color palette includes orange, red, and green with warm tones present throughout. It is one of the softer sub-styles in the catalog — thin 1px stroke combined with flat color fills creates a very light, soft visual presence. It is among the friendliest sub-styles in the catalog — multi-color icons are inherently approachable, with color variety signalling informality. It is one of the more playful sub-styles in the catalog — high color variety and flat illustration-style fills read as distinctly playful. On its human↔mechanical character, it is one of the more human-feeling sub-styles in the catalog — color differentiation per element feels expressive and human, not systematic.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Poppins — rounded geometric with warmth, compatible with multi-color expressiveness
- **Alternative**: Nunito — explicitly rounded, very friendly, matches playful Colors energy
- **Body**: DM Sans (Regular) — clean, non-competing body text
- **Avoid**: Cold geometric sans (Neue Haas), serif at any weight — creates jarring contrast with colorful flat icons
