Nowhere have I been able to see an example of using a color other than a shade of gray to color the labels revealed in LaTeX by \usepackage{showkeys}.

For example, suppose I want labels to be revealed in a (light) green and the refs to those labels to be labeled in a (light) red or, better yet, a (light) pink. How does one do this?

I'm well aware that \usepackage{show keys} "colors" the keys — but unfortunately the color is always gray. How change that?

The package showkeys uses following code


in order to set the colour. refkey and labelkey are both set to a light gray 'colour'. It is sufficient to use a different definition of the refkey and labelkey colours.

  • @murray: Sometimes (or very often? ;-)) it's necessary to dive into the .sty file ;-)

  • Now I need to figure out what named colors are available. I'm using pdflatex from TeXShop's menu system and haven't a clue what driver is being used. Or is there some other way to find out?

  • @murray: See the xcolor documentation: There's a lot of information which colour names are available. You can name your colours of course yourself as you like

  • Will using package xcolor cause any difficulty in that usepackage[color]{showkeys} already automatically causes package color to be loaded?
