Convert color values between formats instantly — everything runs in your browser.
Enter a hex color code (like #5151e5) and get its exact RGB values with a live color swatch.
Hex codes (e.g. #5151E5) pack red, green and blue into a single 6-character value and are the default in most design tools, while RGB (e.g. rgb(81, 81, 229)) lists each channel as a 0–255 number and is what CSS functions like rgba() require when you need to control transparency. Both describe the exact same color — converting between them is just a change of notation, not a change of appearance.
