Previews a palette on a real page layout instead of five swatches.
Five squares tell you nothing about how colours behave as headings, body text, buttons and backgrounds. This drops your colours straight into a sample landing page, flips between light and dark, and shows the contrast ratios changing as you tune. Export gives you CSS custom properties or a Tailwind config.

No. Realtime Colors does the work inside your browser, so the file never leaves your device — you can load the page, disconnect from the network, and it still works. That makes it a reasonable choice for material containing personal data.
