What Is a Color Code Converter and Why Do You Need One?
A color code converter is a simple utility that translates a single color between the formats web designers, developers, and digital artists use every day — HEX, RGB, and HSL. Instead of manually calculating values or guessing how a shade will render in CSS, this free online tool does the math instantly, so you always get an accurate, ready-to-paste color code for your project.
Whether you're building a website, styling a mobile app, matching a brand palette, or just picked a color you love and want its code, a reliable converter saves time and eliminates costly formatting errors. This tool from Floan is built to be fast, accurate, and fully mobile-friendly — no sign-up, no downloads, just instant conversion.
HEX, RGB and HSL — What's the Difference?
Every color on a screen is described using one of a few standard formats, and knowing when to use each one matters for clean, maintainable code.
HEX Color Codes
HEX (hexadecimal) codes like #FF7B9C are the most common format in web design. They're short, easy to copy, and universally supported across CSS, HTML, and design software like Figma and Photoshop.
RGB Color Values
RGB values such as rgb(255, 123, 156) express color as a mix of red, green, and blue light on a 0–255 scale. RGB is intuitive for developers who need to adjust brightness or blend colors programmatically.
HSL Color Values
HSL stands for Hue, Saturation, and Lightness — for example hsl(345, 100%, 74%). This format is favored by designers because it's easier to reason about: keep the hue fixed and just adjust lightness to create tints and shades of the same base color.
How to Use This Color Code Converter
- Type a HEX value (e.g.
ff7b9c) or RGB values (e.g.255,123,156) into the input box, or pick a color visually with the color wheel. - Click Convert to instantly generate the matching HEX, RGB, HSL, and closest CSS color name.
- Click any result card to copy that value straight to your clipboard.
- Hit Reset to return to the default color at any time.
The tool works entirely in your browser, updates in real time, and is optimized for both desktop and mobile screens — so you can convert color codes on the go.
Common Use Cases
- Web development: Quickly convert a brand's HEX code to RGB for use in
rgba()transparency values. - UI/UX design: Translate HSL values to fine-tune lightness while keeping a consistent hue across a design system.
- App development: Match color codes between design tools and code (Swift, Android XML, Flutter, and more accept HEX or RGB).
- Branding: Verify a logo color renders identically across print (CMYK-adjacent) and digital (RGB/HEX) formats.

Frequently Asked Questions
What is the HEX code for a color?
A HEX code is a six-digit hexadecimal number (three pairs for red, green, and blue) that represents a specific color, always prefixed with a #, such as #FF7B9C.
How do I convert RGB to HEX?
Each of the three RGB values (0–255) is converted to its two-digit hexadecimal equivalent and combined. This converter automates that calculation instantly — just enter the RGB values and click Convert.
Is this color converter free to use?
Yes. This color code converter is completely free, requires no account, and works on any device with a modern web browser.
Can I find the CSS name of a color?
