About this icon

Use the Brain Bold icon

The Brain Bold icon (Phosphor) is categorized under Weather. Its bold style is optimal for interface components and product UI and scales cleanly from 16px to 512px.

Use the IconStash detail panel to preview with a custom background, adjust stroke width, and generate production-ready SVG or PNG files without any external tools.

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 Bold icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Phosphor draws Brain Bold 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 Bold 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 { BrainBold } from 'phosphor-react';

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

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