<p>Flex is all about the curves. Its smooth curves brings fluidity and dynamism to your designs with a modern appeal.&nbsp;The Neon style is especially effective in complex environments where&nbsp;quick recognition and hierarchy&nbsp;are essential. It also allows you to customize the line thickness.&nbsp;All Flex Neon icons are designed on a 14px grid with a 1px default stroke and two customizable line colors.</p>

**Summary**: Flex's vivid dark-adjacent sub-style — 1px organic line in magenta and dark navy, delivering neon energy with a refined, delicate quality that thick-stroke neon sets cannot achieve. The thin organic stroke is delicate enough that the neon palette reads as high-design rather than aggressive, making this the most refined neon sub-style available across all families. The tone signals vivid restraint: "we are vivid but not aggressive." Best for creative tools, music and audio platforms, and dark-UI products that want neon energy without the visual aggression of thick-stroke neon — requires a design system that can absorb electric colour without the palette overwhelming the layout.

## Visual & Technical Specs

| Stroke weight | 1px |
| Fill | None (line only) |
| Corner treatment | Smooth fluid curves |
| Color | Magenta/pink primary + dark navy |

### Emotional Scores

Flex Neon is somewhat mechanical on warmth — magenta and navy is an electric, cool palette, though the organic 1px stroke softens the coldness noticeably. It is among the softest sub-styles in the catalog — the 1px organic curves in neon colours remain visually soft; the colour is vivid but the line is delicate. It is somewhat friendly — the neon palette is intense, but the delicate organic curves create a more refined neon register. It is near neutral on playfulness — high colour energy suggests play but thin organic lines suggest refinement, producing a genuine midpoint. On its human↔mechanical character, it is near neutral — the neon colour adds a machine register while organic curves soften this considerably.

## Pairing & Compatibility

### Typography pairing

- **Primary**: Space Grotesk — geometric with subtle personality, handles the neon palette; mild irregularity echoes Flex's organic variation
- **Alternative**: Plus Jakarta Sans Medium — humanist warmth on dark backgrounds
- **Body**: Inter Medium white on dark
- **Avoid**: Cartoon-rounded display (Nunito, Fredoka) — too casual for Flex Neon's refined register


<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>
