Any Good Ethanol Soluble Pigments?

I'm putting together a little setup with an alcohol lamp and an ethanol 
spray bottle, and I figure that I might as well use it to make colored 
flames, rather than just the nearly invisible blue flame of the ethanol.  
?:)

Can anybody recommend any ethanol soluble pigments (I guess that they 
wouldn't be salts, would they) to mix in there, to make green, blue, red
or 
orange flames.  Lord knows, the most obvious choice, copper sulfate won't 
do anything interesting, and it will just make things worse by clogging up

my spray bottle.  ?:(
