Every tool runs entirely in your browser. Nothing you type is uploaded, stored, or logged on our servers.
The Quick Theme Palette Generator lets you create accessible light and dark mode color palettes with real-time contrast validation. It uses the official WCAG 2.1 algorithm to ensure your primary, secondary, accent, and background colors meet key AA or AAA accessibility requirements.
You can adjust colors manually, randomize fully compliant palettes, preview them in an interactive UI, and export your final theme as CSS variables or JSON. The entire tool runs in your browser, making it fast, responsive, and ideal for designers and developers building modern, accessibility-focused interfaces.
