RGB to HEX

Both RGB and HEX represent the same color information but in different formats. RGB uses three decimal numbers (0-255) for red, green, and blue components. HEX uses a six-character hexadecimal string where each pair represents the same components in base-16 (00-FF). They produce identical colors when rendered correctly.

HEX is commonly used in CSS and HTML for its compact format and widespread browser support. RGB is useful when you need to dynamically adjust color values with JavaScript, or when working with opacity using the rgba() format. Many developers prefer HEX for static colors and RGB/RGBA for dynamic or semi-transparent colors.

3-character HEX codes are shorthand for 6-character codes where each pair of characters is identical. For example, #F00 is equivalent to #FF0000, and #123 is equivalent to #112233. This shorthand works when both characters in each RGB pair are the same, reducing the code length while maintaining the same color value.

HEX codes can represent the same 16,777,216 colors as 8-bit RGB values (256 × 256 × 256). However, HEX doesn't natively support alpha (transparency) channels, unlike the rgba() format. For transparent colors, you would need to use RGBA or the 8-character HEX format with alpha (#RRGGBBAA) which is supported in modern browsers.

This converter uses precise mathematical conversion between decimal RGB values and hexadecimal representation, ensuring 100% accuracy for the 8-bit RGB color space (values 0-255). The conversion is deterministic, meaning the same RGB input will always produce the same HEX output, matching industry standards used in web browsers and design software.
