<p>Streamline Vault. Kameleon Duo features dual-tone flat icons in bright colors for friendly, accessible interfaces.</p>

**Summary**: Flat illustration inside solid two-tone blue circle containers on a 48px grid. The most professional and controlled Kameleon variant, with the blue tonal system adding structured order that the warm-palette variants lack. The tone signals disciplined illustration: the same circle-container format with colour restricted to a brand-blue palette, signalling systematic care over expressive energy. Best for consumer SaaS marketing with a controlled blue brand palette and feature sections where colour discipline must be maintained alongside illustration warmth; subject to the same 2014–2018 flat illustration durability caveat as other Kameleon sets.

## Fit & Recommendation

### Primary use cases

- Consumer SaaS marketing with controlled blue brand palette
- Feature sections where colour discipline matters alongside illustration warmth

**Durability note**: The flat illustration aesthetic peaked in 2014–2018. Reads as slightly dated to design-literate audiences in 2025. Most durable in marketing and presentation contexts.

### Emotional Scores

Vault Kameleon Duo is somewhat cold — the blue two-tone system of consistent light blue and dark blue creates an ordered, neutral-cool palette. It is one of the more human-feeling sub-styles in the catalog on softness — circular containers remain soft and the single palette adds structure without hardness. It is one of the friendlier sub-styles in the catalog — the blue tonal system introduces a professional register while circle containers prevent full formality. It is near neutral on playfulness — colour restriction creates systematic order while the set remains clearly consumer-facing. On its human↔mechanical character, it is near neutral — systematic blue-on-blue creates regularity while flat illustration content retains creative quality.

### Typography pairing
