I don't have a problem actually, but want to ask about one feature if it exist in Conky. I'm using Conky variable ${tail} or ${head} to list content of log files. So, for instance I got file with such content:

load: 75
disc: 45
files: 100

And for example ${head} outputs file as is all in one color, but i want to supply ${color} option to digits to be more distinguishable from main text. Is it possible with Conky to do so ?
