Change color of "exec" light?

Hi all, Is there a way to change the color of the "exec" light on the 737NGX? I hope that, over time, I'll learn when to push it, but right now, there's not enough contrast between the background and the light. I'd *really* like to have a high-contrast color like yellow or green for the CDU displays, but I realize we're going for strict authenticity here. I strongly doubt the FAA would be letting me drive a 737 any time soon anyway. On the other hand, Vic did a stunning job on the VC. If I zoom in enough, everything is readable. What a difference!
