RGB defines a color using three numbers from 0-255 representing Red, Green and Blue light intensity, e.g. rgb(255, 87, 51). It is the native format for screens and is widely used in CSS, design software and image editors.

HEX represents the same values as a 6-digit base-16 code prefixed with #, e.g. #FF5733 — two digits each for red, green and blue. HEX is compact and is the most common way to specify colors in CSS, HTML and design tools like Figma or Photoshop.

What this converter does

RGB defines a color using three numbers from 0-255 representing Red, Green, and Blue light intensity, for example rgb(255, 87, 51). It’s the native format for screens and is widely used in CSS, design software, and image editors. HEX represents the same values as a 6-digit base-16 code prefixed with #, for example #FF5733, two digits each for red, green, and blue. HEX is compact and is the most common way to specify colors in CSS, HTML, and design tools like Figma or Photoshop.

rgb(255, 87, 51) = #FF5733 (each channel converted from base-10 to base-16)

Why RGB is the “native” format and HEX is derived

Screens fundamentally work by combining Red, Green, and Blue light intensities, which is exactly what RGB expresses directly. HEX is simply a more compact string representation of the same three numbers, converted to base-16, making it shorter to write and easier to embed in CSS and HTML, even though the underlying color information is identical.

Frequently asked questions

How do I convert RGB to HEX?

Convert each of the Red, Green, and Blue values (0-255) into a two-digit base-16 (hexadecimal) number, then concatenate all three pairs with a # prefix, for example rgb(255, 87, 51) becomes #FF5733.

Is RGB or HEX the “real” color format?

Neither, they represent the identical color information, RGB expresses it as three base-10 numbers, while HEX expresses the same values as a compact base-16 string. Screens work directly with RGB values internally, but HEX is just a shorter way to write the same data.
