Thanks for your interest in our dual oscillator module! You're in luck perhaps. We already have a way to change colors in the UI. If you hit the INFO (edit) button to access the main edit menu, you can press the SYSTEM to access the settings for COLOR A and COLOR B. The choices of color are:
red
blue
green
orange
yellow
cyan
violet
white
Hopefully some combination of those colors will work for you. Are you able to check it out in a local store?
All the best,
Taiho
