Description of use
Converts three 8-bit numbers to hexadecimal.
Useful for all sorts of color-related nefarious purposes.
Input
  • three parameters, each numeric in the range 0..255 (larger numbers will wrap around)
  • #= (optional) allows you to change or remove the prefix for hex numbers (such as #) ; the default prefix is " #" (with a leading space to avoid the internal interpretation by MediaWiki as a numbered list item when returning the value from the template ; this space does nos alter the CSS validity of the value).
  • subst=subst: (optional) allows to perform a permanent substitution of the internal sub-expressions (or subtemplates that may be used), and keep only the result of the evaluations when saving a page using this template. You should pass this parameter in addition to calling the template using the "subst:" prefix that just performs a permanent template expansion and permanent substitution of parameters. (See examples below).
Output
  • a triplet of two-digit hex numbers
Examples
  • {{Hex3|0|0|0}}gives #000000
  • {{subst:Hex3|0|0|0|subst=subst:}} gives #000000
  • {{Hex3|123|45|67}} gives #7B2D43
  • {{subst:Hex3|123|45|67|subst=subst:}}gives #7B2D43
  • {{Hex3|255|255|255}} gives #FFFFFF
  • {{subst:Hex3|255|255|255|subst=subst:}} gives #FFFFFF
See also
  • {{RGB}} for formating as a "rgb(r,g,b)" value
  • {{Hex2}} if you don't want three all at once.
