Mathematica: how to have text in multiple colors?

Question

I'd like to have a manipulate control, something like {{wAB, 1, "AB"}, 0, 1, Appearance -> "Labeled"}, but would like the A and the B to be different colors, say, Red and Blue.
I can change the overall color with Style["AB",Red], but haven't been able to get the A and the B in different colors. Any help would be appreciated!

Answer 1

you mean like this?

Manipulate[
 wAB,
 {{wAB,1,Row[{Style["A", Red], Style["B", Blue]}]},0,1,Appearance->"Labeled"}
 ]

and if you prefer to define the decoration part separately (which can be useful for larger and more complicated controls) and reference it in controls later on (like declaring a variable, sort of, but it is a macro actually) and reuse it for different controls, then you can use With, like this

Manipulate[wAB,

 Evaluate@With[

   {myStyle = Row[{Style["A", Red], Style["B", Blue]}]},

   {{wAB, 1, myStyle}, 0, 1, Appearance -> "Labeled"}

   ]
 ]
