Yep, you can. You will have to take apart the switches, remove the green caps from the bulbs, and paint them with a transparent blue paint, which you can find in just about any hobby shop. As for the message center, if you take it apart you will find that the cover over the LED readout is glass, which appears green tinted but it is actually a coating that you can scrape off with a razor blade. Once you get it cleared off you just put a piece of blue gel film (what they use for stage lights) over the glass sandwiched between it and the plastic cover. Good luck!
