[AccessD] Changing colors on many controls on one Form

Good morning all
 
I've just been asked by a user if the backcolor can be changed when that  
control has got focus and changes back to original when it looses focus. Yeah  
thats OK I can handle that no problems. But with 30+ controls going to each  
control and adding one line of code to change the backcolor and change  it back 
on each got and lost focus property is a pain. And next week the  user will ask 
"can we have a different color".
 
This job labour intensive so is there a more elegant approach to this  simple 
but boring job??
 
TIA
