I'm trying to do up a resume in LaTeX however I'm wanting to use a different color for the footnote markers so that it's clear that they are not part of the normal text.
PHP, Java, C\footnote{It has been many years since I've used this in a project}, Python
This results in the following, which ends up looking like C^1:
How do I change the font color of the "1" to a light grey so that it's more obvious that it's separate from the main body of text.

It all depends on exactly what do you want to colorize since there are three possible elements involved: 1) the mark used in the text to signal the footnote, 2) the mark used at the bottom of the page where the actual footnote text appears, and (possibly) 3) the mark used when cross-referencing the footnote. In the following examples I used the color
red
just to highlight the different results:A redefinition of
\thefootnote
(like some other answers suggest) will affect all these three elements:If one only wants to change color to elements 1) and 2) (the marks in the body and in the actual footnote text) but not to 3) (the number used in cross-references), then a redefinition of
\@makefnmark
will be needed:Finally, if the change of color must affect only the mark used in the body of the document without affecting the mark used in the footnote text or the number used in cross-references, then redefinitions of
\@makefnmark
, and\@makefntext
will be needed:
