How to Use the Color Converter

This free online color converter transforms colors between HEX, RGB, and HSL formats instantly with interactive sliders and a visual color picker. Whether you're converting a hex color code to RGB values, finding the HSL equivalent for CSS animations, or looking up the closest Tailwind CSS class for a brand color, this tool gives you every format you need in one place — all running in your browser.

Step-by-Step

1. **Enter a color** — Type a HEX value (#FF5733), RGB values (rgb(255, 87, 51)), or HSL values (hsl(14, 100%, 60%)) into the corresponding input field.

2. **Use the sliders** — Adjust the interactive color sliders (Hue, Saturation, Lightness, or R, G, B channels) to fine-tune your color visually.

3. **View all formats** — The tool instantly shows the color in HEX, RGB, HSL, Tailwind CSS class, and CSS custom property format.

4. **Copy any value** — Click Copy next to any format to grab it for your stylesheet, design tool, or code.

Features

- **Three-way conversion** — Enter a color in any format (HEX, RGB, or HSL) and see all other formats instantly.

- **Interactive sliders** — Adjust hue, saturation, lightness, red, green, and blue channels with visual sliders.

- **Visual color preview** — A large color swatch shows the selected color in real-time.

- **Tailwind CSS output** — Get the closest matching Tailwind CSS color class (e.g., bg-red-500) for rapid utility-class styling.

- **CSS variable format** — Copy the color as a CSS custom property ready for your design system.

- **Real-time updates** — All formats and the preview update instantly as you modify any input.

- **100% client-side** — All color math runs in your browser. No data is transmitted anywhere.

Common Use Cases

1. **Design-to-Code Conversion** — Designers provide colors in HEX. Convert them to RGB for JavaScript canvas operations, or HSL for CSS animations that need to animate hue or lightness.

2. **Tailwind CSS Development** — Find the closest Tailwind utility class for a brand color, or convert custom HEX values to Tailwind's bg-[#FF5733] arbitrary value syntax.

3. **CSS Custom Properties** — Generate CSS variable declarations for design systems: --color-primary: hsl(14, 100%, 60%).

4. **Accessibility Contrast Checking** — Convert colors to HSL to easily adjust lightness for WCAG contrast ratio compliance without changing the hue.

5. **Cross-Platform Development** — iOS uses RGB, Android uses HEX, CSS uses all three. Convert between formats for consistent colors across platforms.

Tips for Power Users

- HSL is the most intuitive format for color manipulation — adjust lightness for hover states, saturation for muted variants, and hue for color scheme generation.

- For accessibility, use HSL and ensure sufficient lightness difference between text and background colors.

- Tailwind's color palette uses carefully chosen values. The closest-match feature helps you stay within Tailwind's design system while working with custom brand colors.

- Use this tool alongside the CSS Gradient Generator to convert colors before adding them as gradient stops.

- When working with opacity, remember that HEX supports alpha values (#FF573380 = 50% opacity) in modern browsers.
