Traditional color pickers give you one color. The Dracula theme gives you 10 carefully curated colors. But complex designs need hundreds of colors that work together.

This solves the original Dracula bottleneck by providing hundreds of systematically generated colors that maintain the Dracula aesthetic while offering the variety needed for complex designs.

Support for 10 modern color standards organized by use case:

• Material Design 3, HSLuv, OKLCH

• HCL, CAM16-UCS, IPT, Cubehelix

• CIE LAB curves

• Color Harmony, HPLuv

• Perceptually Uniform Calculations with OKLCH-based similarity scoring
• WCAG Accessibility Compliance with "Make Accessible" button for contrast ratios
• Multiple Export Formats: Individual colors (HEX, RGB, HSL, OKLCH, LAB) and palettes (CSS, SCSS, JSON)
