<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Pop style is useful for projects that need a colorful touch, helping to capture attention and strengthen brand recognition.&nbsp;All Flex Pop icons are designed on a 14px grid with a mix of outlined and filled shapes, including a wide color palette.</p>

**Summary**: Flex's consumer colour sub-style — organic curved construction with navy primary and warm saturated fills (yellow, coral, teal, green), delivering colour energy with a refined, flowing quality that geometric multi-color sets cannot match. The organic curved construction elevates the colour energy from casual to considered. The tone signals living colour: "we are alive with colour and curve." Best for modern consumer apps needing colour-based feature differentiation with visual quality, wellness and lifestyle products, and landing pages for consumer SaaS with strong brand colour where organic refinement is part of the brand signal.

## Visual & Technical Specs

### Visual properties

| Property | Value |
|----------|-------|
| Stroke weight | Variable |
| Fill | Mix outlined + filled per element |
| Corner treatment | Smooth fluid curves |
| Color | Navy primary + yellow, coral, teal, green saturated fills |

### Emotional Scores

Flex Pop is one of the warmer sub-styles in the catalog — navy and warm saturated fills on organic curved forms combine colour warmth with the warmth of organic form. It is one of the softer sub-styles in the catalog — colour fills and organic curved construction prevent hardness from being perceived. It is one of the friendlier sub-styles in the catalog — multi-color organic forms read as inviting and modern, less casual than geometric Pop equivalents. It is one of the more playful sub-styles in the catalog in a refined register — colour energy and organic curves create a fresh, light quality that is more considered than outright playful. On its human↔mechanical character, it is one of the most human-feeling sub-styles in the catalog — warm colour expressiveness and organic curves sit firmly in the human register.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Plus Jakarta Sans — humanist warmth handles multi-color organic icon environments without becoming competitive
- **Alternative**: Outfit Medium — clean, slightly warmer than Inter
- **Display**: Syne ExtraBold — organic flowing display weight for campaign contexts
- **Body**: DM Sans Regular
- **Avoid**: Rounded display fonts at display weight (Nunito, Poppins, Fredoka) — the cartoon register conflicts with Flex's organic refinement


<p>Flex is a fluid icon family inspired by nature’s curves. It favors smooth, flowing forms. More organic than Core and subtler than the chunky Plump. Read about the <a href="https://blog.streamlinehq.com/flex/" rel="noopener noreferrer" target="_blank">design process</a>.</p>
