<p>Plump is highly inspired by cartoons. With its warm appearance, this set of chunky icons is a natural choice for friendly brands.&nbsp;The Flat style is easy to integrate into projects that need icons with a more illustrative purpose, working best at larger sizes. All Plump Flat icons are designed on a 48px grid with two customizable colors.</p>

Plump Flat

**Summary**: Plump's illustrative sub-style — solid two-tone blue fills on chunky rounded silhouettes, suited to onboarding illustrations and feature explainers at large display sizes where the inflated shapes create warmth in the flat register. Chunky rounded silhouettes create significantly more warmth than slim geometric flat sets at the same blue tonal palette, and the blob-adjacent organic quality carries through even in the two-tone illustrative mode. The tone signals illustrative warmth: "we illustrate warmth, not structure." Best for onboarding and product tour illustrations at 40px+, feature explainer sections, and educational content for children and young users.

### Emotional Scores

Plump Flat is one of the warmer sub-styles in the catalog — the blue tonal system is cool, but chunky rounded silhouettes create more warmth than slim geometric flat sets at the same palette. It is one of the more human-feeling sub-styles in the catalog on softness — flat fills on chunky rounded shapes have hard fills softened by shape edges. It is among the friendliest sub-styles in the catalog — two-tone blue in cartoon shapes reads as illustrative and approachable. It is one of the more playful sub-styles in the catalog — the chunky flat illustration register is playful by construction. On its human↔mechanical character, it is one of the most human-feeling sub-styles in the catalog — rounded blob shapes are organic and illustrative, not schematic.
