Is there a way to define a button's color with a variable? I have a particular button whose purpose is to show me the status of a complex multistate trigger, and I would like it to change color depending on what state the trigger is in. I've tried defining the button with a color of @buttoncolor, then changing the value of @buttoncolor, but it takes the value when first defined, but won't change.

I've considered using a statusline, which I can change the color of with a variable, but I use that for another purpose.

I also tried playing with a multistate button to see if I could just set different states for different colors, but I'm having little luck. Besides, having the little drop-down arrow reduces how much room on the button I have for the caption.

I'm open to other suggestions...

Sure you can. %btncol is a function and can be used directly in the caption of the button. Of course since it is a function it returns a value, and you don't really want that to show up in the caption. To overcome that we simply use another function that we can have always return null.
%if(%btncol(IDofButtonIwantColored,@buttoncolor))
Voila, the button automatically changes color. I do similar things with %btnenable to have buttons turn on and off when those potrions of my scripts are unavailable, but I don't want the layout to shift.

I'd give the button an id if you haven't done so already, then use
#CALL %btncol( button_id,new_color,)
in each state of the trigger.

Awesome. I'll have to play with it next time I'm at my PC....
