From RGB to HEX, explained

RGB describes a color with three numbers from 0 to 255, one each for red, green, and blue. A hex code packs those same three numbers into a compact string by writing each as a two-digit hexadecimal value. For example, rgb(109, 139, 255) becomes #6d8bff: 109 is 6d, 139 is 8b, and 255 is ff. The converter handles this math for you and always pads single digits so the code is valid.

How to use it

1. Set the Red, Green, and Blue sliders, or type exact values.
2. The hex code and live preview update instantly.
3. Click Copy to grab the hex value.

When you need hex instead of RGB

Hex codes are the most common way to specify colors in CSS, design software, and brand guidelines because they are compact and unambiguous. If you sampled a color as RGB from an image editor, a screenshot tool, or a canvas, converting to hex gives you a portable value you can drop into a stylesheet, a theme file, or a documentation page. Hex is also the format most developers recognize at a glance.

Tips for picking colors

• Pure primaries are easy to remember: red is #ff0000, green #00ff00, blue #0000ff.
• Equal R, G, and B values always produce a shade of gray.
• To darken a color, lower all three channels proportionally; to lighten it, raise them.
