You can do this with LC's built-in horizontal scrollbar. Drag a Slider control to the card. Set 
the start value to 1 and the end value to 3. By default there will be numbers displayed but you 
can turn those off and use labels underneath instead.

Put this script into the slider. It should make the slider snap to one of the three positions:


on scrollBarDrag
   set the thumbPos of me to the thumbpos of me mod(4)
end scrollBarDrag

If you want to change the color, use an effects overlay. None of the built-in color properties 
apply.
