How RGB to HEX Conversion Works
Computers handle colors in various ways, with RGB and HEX being the most common. In web development and programming, you often need to switch between these formats. This tool bridges that gap instantly.
What is RGB?
RGB stands for "Red," "Green," and "Blue"—the primary colors of light. Each component is represented on a scale of 0 to 255. For example, (0, 0, 0) is "Black," and (255, 255, 255) is "White."
What is HEX (Hexadecimal Color Code)?
A HEX code converts each RGB value into a base-16 number (0-9, a-f) and pairs them with a "#" prefix (e.g., #ff0000). This is the most widely used format for specifying colors in HTML and CSS.
The Conversion Math
To convert an RGB value, divide it by 16 and use the quotient and remainder to determine the two-digit hex value.
- Example: If R (Red) is 255
- 255 ÷ 16 = 15 with a remainder of 15
- Since 15 is "f" in hexadecimal, 255 becomes "ff."
