Nice and (hopefully) easy. I am trying to work out how to grab the variable #XXX from a text file (css file) containing strings like

hr { margin: 18px 0 17px; border-color: #ccc; }

h1 a:hover, h2 a:hover, h3 a:hover { color: #001100; }

Which I would like to return as

ccc

777

The plan then is to throw this through sort and uniq and the end up with a defining colourscheme for the page.

Basically, I can't work out how to go from matching /color:#...[...]/ to just printing out the wildcarded sections.
