About this tool

The Gearizen Color Converter is the design-sidekick that translates colors between HEX, RGB, HSL, and alpha-enabled formats with precision. Designers, frontend developers, and brand managers can paste any value and immediately receive synchronized equivalents along with live previews. The tool supports 8-digit HEX, rgba(), and hsla() so you can communicate transparency accurately across design systems and CSS codebases. Because conversion happens in the browser, brand palettes and unreleased product themes remain private while you experiment.

We crafted this page to guide you through practical color workflows. Learn how to harmonize palettes between Figma and CSS, convert developer-provided HEX values into HSL for nuanced tweaks, and create accessible hover states by adjusting lightness. Tips cover device-specific color management, CSS variable strategies, and ways to document palettes for marketing collateral. Color science explanations demystify hue, saturation, and lightness so you can communicate design intent to stakeholders.

SEO-friendly advice answers queries like "How do I convert RGB to HEX?" or "What is HSL color space?" Accessibility sections walk you through contrast checking basics, dynamic theming, and strategies for supporting dark mode. We also share export tips for handing off palettes to developers, including copying CSS snippets, SCSS variables, or Tailwind tokens. With keyboard navigation and responsive layouts, the converter works seamlessly during design critiques or coding sessions.
