Hehe yes I do, I try to minimize the variables I use. Mostly because  
I am not very good at coming up with names for them ;)
Also, influenced from functional programming, I try minimize the  
number of assignments I use.

Why not instead simply give it a default, if string is empty?

string = STDIN.read
string = "#999" if string.empty?
prefix, string = string.match(/(#?)(.*)/)[1,2]
string = $1 * 2 + $2 * 2 + $3 * 2 if string =~ /^(.)(.)(.)$/
def_col = ' default color {' + string.scan(/../).map { |i| i.hex *  
257 }.join(",") + '}'
......
