Tailwind, Material & Bootstrap Color Libraries: limits and things worth knowing

• Material Design uses 50-900 steps, Tailwind 50-950, and Bootstrap a smaller semantic set. The numbering conventions look similar and are not interchangeable.
• Framework palettes are designed as systems, so their mid steps are tuned to work together. Mixing a Material 500 with a Tailwind 500 often looks slightly off.
• Palettes change between major versions — Tailwind v4 redefined its colours in OKLCH — so check which version a value came from.
• Most framework mid-tones fail WCAG AA against white for body text. Verify before using them for type.

Is it private and secure?

Your privacy is built in. Tailwind, Material & Bootstrap Color Libraries runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
