<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Gradient style is best suited for designs where impact and immersion are key, especially on dark backgrounds. All Flex Gradient icons are designed on a 14px grid using filled shapes as gradient colors.</p>

**Summary**: Flex's most expressive sub-style — full-spectrum multi-stop gradient fills on fluid organic silhouettes, creating a distinctive high-production marketing presence that geometric gradient sets cannot replicate. Flowing organic edges amplify the warm gradient stops in a way that flat geometric fills cannot. The tone signals expressive flow: "we are expressive and flowing." Best for high-production landing pages, hero sections, and brand marketing at display sizes where flowing gradient silhouettes create visual distinction from geometric gradient equivalents.

### Emotional Scores

Flex Gradient is one of the warmer sub-styles in the catalog — full-spectrum gradients with warm tones on organic silhouettes allow flowing shapes to amplify the warm gradient stops. It is one of the softer sub-styles in the catalog — gradient fills on organic silhouettes with flowing edges prevent the hardness of flat geometric fills. It is one of the friendlier sub-styles in the catalog — rainbow gradients in flowing shapes read as expressive and contemporary. It is one of the more playful sub-styles in the catalog in a refined way — gradient energy with organic forms reads as creative and modern, more refined than outright playful. On its human↔mechanical character, it is one of the most human-feeling sub-styles in the catalog — colour expressiveness combined with organic silhouettes reads as human creative expression.

## Pairing & Compatibility

### Typography pairing

- **Body**: Outfit Regular or DM Sans
- **Avoid**: Cold geometric grotesque; cartoon rounded display fonts


<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>
