<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Flat style is easy to integrate into projects that need icons with a more illustrative purpose, working best at larger sizes. All Flex Flat icons are designed on a 14px grid with two customizable colors.</p>

**Summary**: Flex's illustrative sub-style — solid flat two-tone blue fills on fluid organic silhouettes, producing a more contemporary and natural-feeling flat illustration register than geometric flat sets. Fluid organic edges soften the flat fill quality, making this register warmer and more natural than Sharp Flat or Core Flat at equivalent blue tonal palette. The tone signals organic illustration: "we illustrate nature's geometry." Best for onboarding and product tour illustrations at display sizes, feature explainer content in modern consumer products, and marketing where organic silhouettes feel more contemporary than geometric flat alternatives.

### Emotional Scores

Flex Flat is somewhat warm — the blue tonal system is cool, but organic silhouettes add warmth that geometric flat sets lack. It is one of the friendlier sub-styles in the catalog — flat fills on organic silhouettes produce flowing shape edges that soften the fill. It is one of the friendlier sub-styles in the catalog — the two-tone blue in organic shapes reads as modern and considered, with mild approachability. It is somewhat warm on playfulness — organic flat illustration reads as contemporary and considered rather than playful or severe. On its human↔mechanical character, it is one of the more human-feeling sub-styles in the catalog — fluid organic silhouettes read as natural forms, not diagrams.

<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>
