About the Brightness black outline icon
A small open circle sits at the center of a larger circular frame, surrounded by eight evenly spaced straight rays of matching length. The form is read universally as brightness, daylight and screen luminance control. Use it for display settings panels, brightness and contrast sliders, light and dark mode toggles, camera exposure controls, or weather app conditions.
Even ray spacing and a generous gap between core and rays keep the mark from looking cluttered at small sizes, and the outer circle lets it sit as a button beside volume and contrast icons in the same set. Below 20px the rays begin to blur, so prefer 24px in toolbars.
This is the black outline version of the brightness icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
