From readable colors to CSS

Start with Contrast Checker for text and background pairs, then use Palette Generator for supporting colors. Build variations with Color Shades Generator and recheck the pairs you intend to use for text. Finish with Gradient Generator for CSS backgrounds or CSS Box Shadow Generator for elevation.

Where do my design values go?

Color values and generated styles are processed on your device. The site's content security policy allows connections back to this site only (connect-src 'self'). Some tools load their engines or models from this site on first use; local processing does not mean that loading the page makes no network requests.
