There are two things to worry about here.  How do you get the visual 
feedback you want, and how do you detect the action.  Detecting the 
action is the same as before.  You need to detect the button changes via 
value change events, mouse or key events, etc.  Build small state 
machines to keep track of what you have seen and which transitions are 
valid.

For the visual changes, most of them will be done via property nodes. 
Towards the bottom, the property node for a Boolean gives you access to 
the Boolean Text's font and to the properties like Bold that can be changed.

If you just want three colored sections behind the controls in this 
panel, place three graphical decorations.  LV has built in rectangular 
decorations, or you can import a bitmap if you like.  Use the cycling 
arrows or Ctl-Shift-J to move the graphics to the back of the controls. 
  If you want this color to change, use an indicator instead -- the 
color control works pretty well, but so does the ring, the Boolean, and 
the color ramp.

If you want to have three panels displayed in one window, you need to 
look at using the subPanel feature in LV7.
