The layered fill system produces a gentle visual depth that feels modern and considered rather than flat or heavy. The tone signals personality and brand expressiveness: color hierarchy built into the icon itself rather than into the surrounding layout. Best for marketing pages, onboarding flows, and feature sections where icons carry brand color and visual dimension beyond standard UI chrome." --- # Ultimate Duotone 1px stroke with a three-layer fill system (colored stroke + colored tint fill + selective white fill), rounded throughout, color-customizable — the most expressive and depth-forward Ultimate sub-style for UI work. The layered fill system produces a gentle visual depth that feels modern and considered rather than flat or heavy. The tone signals personality and brand expressiveness: color hierarchy built into the icon itself rather than into the surrounding layout. Best for marketing pages, onboarding flows, and feature sections where icons carry brand color and visual dimension beyond standard UI chrome. License: Commercial ## Fit & Recommendation ### Primary use cases - Marketing pages and feature differentiation sections - Onboarding flows and empty states - Landing page sections where icons carry more visual weight than UI chrome - Products with a defined brand color where icons should reflect it - Hero visuals that need depth without full illustration --- ## Visual & Technical Specs ### Visual properties | Property | Value | |----------|-------| | Stroke weight | 1px | | Fill | Three-layer: colored stroke + colored tint fill + white fill applied selectively | | Corner treatment | Rounded | | Color | Teal/cyan default (customizable to brand color) | ### Emotional Scores Ultimate Duotone is one of the friendlier sub-styles in the catalog — the default teal/cyan is a cool colour, but the partial fill softens the coldness noticeably, landing as somewhat warm overall. It is one of the softer sub-styles in the catalog — the 1px stroke combined with a low-opacity fill creates a gentle, layered softness. It is one of the friendlier sub-styles in the catalog — the colour and fill combination reads as inviting rather than formal, leaning clearly friendly. It is one of the more playful sub-styles in the catalog — the two-tone colour adds personality and levity; not fully playful but clearly expressive. On its human↔mechanical character, it is one of the more human-feeling sub-styles in the catalog — colour warmth combined with fill depth humanises the icons visually. --- ## Pairing & Compatibility ### Typography pairing - **Primary**: Plus Jakarta Sans — rounded, slightly personality-forward, matches the tonal depth - **Alternative**: Poppins — geometric warmth, compatible with color-forward icons - **Body**: Inter or Mulish in Regular weight - **Avoid**: Monospace fonts (personality mismatch); serif display at high contrast ## Categories - [Interface Essential](/icons/streamline-duotone/interface-essential) - [Technology](/icons/streamline-duotone/technology) -
