4k Icon
4k · Essentional Ui · 6 styles
4k sits in the Essentional Ui shelf of the Solar Icons library. It is one of 139 glyphs in that category and one of 1,246 icons in the library overall, each drawn on the same 24x24 grid so 4k lines up optically with everything around it. The icon is addressed in templates by the string "4k", and every style variant resolves from that single name.
In practice it stands for the idea of the primitives every interface needs — add, close, check, menu, info, danger. That places 4k in the Essentional Ui family, which covers the primitives every interface needs — add, close, check, menu, info, danger and turns up in buttons, dialogs, toasts, form validation and empty states. Teams building literally every application, which is why it is the largest set here reach for this set first. Use 4k where the label alone would be ambiguous — an icon-only button, a dense table row, a mobile tab bar — and keep an accessible name on the control, because the SVG itself is decorative.
4k in 6 styles
4k is available in 6 style variants: Bold, Bold Duotone, Linear, Outline, Broken and Line Duotone. Bold gives you solid filled shapes that hold their weight at 16px and read clearly against coloured backgrounds. Bold Duotone gives you a filled body with a second, lower-opacity layer that adds depth without a second colour token. Linear gives you even 1.5px strokes, the neutral default for dense interfaces and toolbars. A common pairing is Bold for the selected state and Line Duotone for the rest, so the active item reads without a colour change.

Because each export is a separate binding, unused variants are dropped by the bundler. Import KBold from the "@rchernando/solar-icons/essentional-ui" entry point, hand it to provideSolarIcons in your application config or in a route-level providers array, and render it with the solar-icon component. All 6 exports for 4k live in that same entry point, so switching style is a one-line change.

Icons drawn alongside it in Essentional Ui include Sleeping, Bolt Circle, Flag2, Mention Circle, Subtitles, Confetti, Glasses and Paw. They share stroke weight and corner radius with 4k, so mixing them in one toolbar stays consistent.
Elsewhere in the library
In other corners of the library, Graph New Up, Vinyl, Notes Minimalistic, Card, Shield Minimalistic and File Send cover neighbouring ideas; the name "4k" is 2 characters long and splits into 1 token, which is how the explorer's search matches it.
4k icon FAQ
- How do I use the 4k icon in Angular?
- Import KBold from "@rchernando/solar-icons/essentional-ui", register it with provideSolarIcons(KBold) and render <solar-icon name="4k" iconStyle="bold" />. No HTTP request is made — the SVG is inlined at build time.
- Which styles does 4k support?
- 6 of them: Bold, Bold Duotone, Linear, Outline, Broken and Line Duotone. Each is a separate export, so you only ship the ones you import.
- Can I change the size and colour of 4k?
- Yes. The size input accepts any CSS length and the SVG uses currentColor, so 4k inherits the text colour of its container — a Tailwind class such as text-violet-400 is enough.
