CSS to distinguish icons for different values

[stianj]

I'm using the "Numeric value display" widget. Is it possible to distringuish the different icons in CSS?

I have a (custom) icon that I want to use for several values, but I would like to change the color. I can do that using the css filter property, but then I need to be able to distinguish the the values using css... 

I can of course also change the color of the icon in an editor and upload 10 different versions - but would prefer if it was possible with CSS... 

Could also be useful with the Switch widget...

Not possible at the moment but we will think of something
