About this icon

Use the Brain Duotone icon

The Brain Duotone icon from Phosphor fits naturally in weather forecast apps, climate dashboards, location-based services, environmental widgets, and IoT sensor displays. Its duotone style makes it ideal for feature highlight cards, onboarding illustrations, content-rich landing pages, and infographics.

Open it in IconStash to set stroke color via presets or a custom hex value, choose an exact pixel size (16–512px), control stroke width (0.1–3px), and preview against dark, light, or checkered backgrounds before downloading.

Export formats

Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.

All exports are based on the same editable vector — so the Brain Duotone icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Phosphor draws Brain Duotone with a uniform stroke weight and generous curves. Its defining feature is a six-weight system — Thin, Light, Regular, Bold, Fill and Duotone — so one concept can carry an entire visual hierarchy without you switching icon families mid-product.

UX best practices

Weather icons are scanned rather than read, so the Brain Duotone icon must stay legible at small sizes and be consistent with the rest of the forecast set. The most common mistake is mixing outline and filled glyphs across one forecast row, which makes a single strip look like two different data sources.

Use in your project

React / npm — Phosphor

npm install phosphor-react

import { BrainDuotone } from 'phosphor-react';

// JSX usage:
<BrainDuotone size={24} weight="regular" />

Copy the SVG markup directly from the IconStash editor to use the Brain Duotone icon without any npm package — paste it into HTML, JSX, or a design tool.
