brilliant.org — design breakdown

Other · Colorful · Illustration

Brilliant — interactive math and science learning. Interactive STEM puzzles, colorful diagram illustration, curious learning. This page breaks down the measurable design decisions behind the site — the extracted color palette, typography, tone of voice — and generates a complete vibe-coding prompt that recreates the same design language in Lovable, Cursor or v0.

What brilliant.org does well

A confident, saturated palette that makes the brand instantly recognizable.
Custom illustration creates a visual language no competitor can copy.

Apply it to your own project

Pick 1–2 signature hues and repeat them everywhere; rainbow dilutes.
A consistent illustration style across the site beats better-but-mixed artwork.

The vibe-coding prompt

Norrly generates a complete founding prompt from the measured values above — theme, exact hex colors, type scale, button geometry, section structure, motion rules and hard constraints. Paste it into Lovable, Cursor, v0 or Bolt to start from brilliant.org's design language instead of AI defaults. A preview:

You are a world-class web designer + frontend engineer. Build an original single-page landing page in the exact design language of brilliant.org (other — Brilliant — interactive math and science learning.) Do NOT clone their content or logo; recreate the FEEL. Every token below was measured from the live site — follow them precisely, they are the product.

Stack: React + Tailwind CSS (works in Lovable, v0, Bolt or Cursor as-is). Single page, production quality, fully responsive.
