RGB to HEX

Både RGB og HEX repræsenterer den samme farveinformation, men i forskellige formater. RGB bruger tre decimaltal (0-255) til røde, grønne og blå komponenter. HEX bruger en hexadecimal streng på seks tegn, hvor hvert par repræsenterer de samme komponenter i base-16 (00-FF). De producerer identiske farver, når de gengives korrekt.

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.

Denne konverter bruger præcis matematisk konvertering mellem decimale RGB-værdier og hexadecimal repræsentation, hvilket sikrer 100 % nøjagtighed for 8-bit RGB-farverummet (værdier 0-255). Konverteringen er deterministisk, hvilket betyder, at det samme RGB-input altid vil producere det samme HEX-output, hvilket matcher branchestandarder, der anvendes i webbrowsere og designsoftware.
