Neon design system

What font does Neon use?

Neon’s website uses Inter for headings and body text. Inter is free on Google Fonts.

Neon colour palette

Neon’s home page is dark (#000000 background, #FFFFFF text) and uses #303236 for its main actions. Its palette: #000000, #E4F1EB, #18191B, #151617, #FFFFFF, #797D86.

Type scale

Each size the page sets text in, with its weight and line height. Neon’s largest type is 98px at weight 400.

Spacing and shape

Spacing sits on a 4px grid: 4px, 8px, 12px, 16px, 20px, 24px, 28px, 32px, 36px, 40px, 44px, 48px.

Corner radii: 4px, 5px, 10px, pill. 3 shadow levels measured.

What makes Neon look like Neon

Almost entirely neutral: 99% of the page is painted in #000000 and #E4F1EB.

#34D59A is an accent: under 0.1% of the page, as small fills such as buttons and badges. Keep it to small areas.

#00E599 is an accent: under 0.1% of the page, as small fills such as buttons and badges. Keep it to small areas.

The largest type (128px GeistMono) is regular weight, not bold (400), tracked to -0.04em.

Neon DESIGN.md for Claude Code, Cursor and Lovable

A DESIGN.md is the brief an AI coding tool reads before it writes UI. This one carries everything on this page as rules a model follows: the allowed colours and what each is for, the fonts with free stand-ins, the type scale, spacing, corners, and the things Neon’s design never does.

Put it in your project root and ask your tool to follow it: “Read DESIGN.md and build [your product] in this design language.” It describes a style, not Neon’s product, so use your own name, words and images.

As CSS variables

The measured values as CSS custom properties, with free fonts standing in for licensed ones. Use them to learn from or to start a project in a similar style; Neon’s name, logo, words and images are theirs.

How this was measured

PikSpec’s scanner read the neon.tech home page in Chrome at 1440px wide on 15 October 2026: the computed styles of its elements, the fonts that rendered and how much of the page each colour covers. Websites change; capture the page yourself with PikSpec for today’s values, any page, and exports in five formats.
