Have you ever looked at white LEDs? They're friggin brite!
I don't think you'll have to worry about not seeing them. And grey pots? So long as you're not colorblind and can see in more than 2 dimensions, you'll see those too!
Besides, How awesome will that look in the dark? Blue is more and more common and tends to hide text on control surfaces. White will look like its daytime above the Virus. I think its a good chice and certaintly a style of their own. Why else would you spell Polar with a Zero?
