RGB to Hex Converter

How to Use the RGB to Hex Converter

Colors on the web are primarily defined using two systems: RGB (Red, Green, Blue) and Hex (Hexadecimal). While monitors display colors using RGB light, web developers (CSS) and designers (Photoshop, Figma) often require Hex codes for precision and brevity.

This tool serves as a bridge between the two formats. Simply adjust the Red, Green, and Blue sliders to visually mix your color, or type exact 0-255 values into the input boxes. The tool instantly calculates the corresponding Hex string (e.g., #FFFFFF) and displays a real-time preview.

Understanding RGB

The RGB color model is an additive color model. It creates colors by adding varying intensities of Red, Green, and Blue light together. Each channel has a range from 0 (no light) to 255 (full intensity).

• RGB(0, 0, 0): Black (No light)
• RGB(255, 255, 255): White (Full intensity)
• RGB(255, 0, 0): Pure Red

Understanding Hexadecimal Colors

A Hex color code is simply a different way to represent RGB values. It starts with a hash (#) followed by six characters (0-9 and A-F).

• The first two characters represent the Red value.
• The middle two represent Green.
• The last two represent Blue.

For example, the decimal number 255 is equivalent to "FF" in hexadecimal. Therefore, pure red (255, 0, 0) becomes #FF0000.

Why do we need to convert?

While modern CSS supports `rgb()` and `rgba()` functions, Hex codes remain the industry standard because they are compact and universally supported across all browsers and design tools. This converter ensures you get the exact code you need without doing the math manually.
