Pro Tip
Always check the accessibility contrast ratios to ensure your design is inclusive. A ratio of 4.5:1 is the minimum for standard text (WCAG AA).

Design System Starter

The Design System Starter is a comprehensive tool designed for web designers and developers to kickstart their design projects with a solid foundation. Whether you're building a new brand or refining an existing one, this tool provides everything you need to create a cohesive and accessible color system.

Key Features

  • Palette Workflow: Generate a complete range of tints and shades (100-900+) from a single primary brand color.
  • Color Harmonies: Instantly generate complementary, triadic, analogous, and other harmony schemes to find the perfect secondary and accent colors.
  • Accessibility Check: Real-time WCAG 2.1 contrast ratio verification for text on backgrounds to ensure your designs are inclusive and readable.
  • Code Export: Copy ready-to-use CSS Variables, SCSS variables, or a Tailwind CSS configuration object to integrate into your codebase immediately.

Why Use a Design System?

A design system ensures consistency across your application. By defining a set of core colors and their variations, you avoid the messy "color creep" that often happens in long-term projects. Moreover, prioritizing accessibility from the start helps you reach a wider audience and complies with modern web standards.

How to use

  1. Select your Primary Color: Use the color picker to choose your main brand color.
  2. Explore Harmonies: Switch through the Harmony tabs to find colors that work well together.
  3. Check Accessibility: Review the Contrast cards to see if your color combinations pass WCAG standards.
  4. Export Code: Go to the Export section to copy the variables into your stylesheet or config file.

Privacy Policy

The Design System Starter is a client-side tool. All color calculations and code generations are performed directly in your browser. We do not store or transmit any of your color choices or design data to our servers.
