Frequently Asked Questions

1. What is a "50-950" color scale?

It's the naming convention popularized by Tailwind CSS: eleven steps from 50 (lightest tint) through 500 (the base color) to 950 (near-black shade), used for consistent UI color systems across buttons, backgrounds, borders, and text.

2. Which step should I use as my base brand color?

Typically 500 or 600 represents your primary brand color, with lighter steps (50-300) used for backgrounds/hover states and darker steps (700-950) used for text and high-contrast elements.

3. Can I export this straight into my Tailwind config?

Yes — generate your shade scale here, then use the Palette to Tailwind CSS export tool to get a ready-to-paste tailwind.config.js snippet or CSS custom properties.

4. Will the generated shades stay accessible for text?

The scale spans a wide lightness range, but you should still verify specific pairings (e.g. 600 text on white) with the Color Accessibility Checker before shipping.
