Change Revel BE driver color to black?

My beryllium tweeters don’t have a screen over them. Should I wear my sunglasses at night ?

No, but you should see your doctor, you might have been poisoned; at least that's what some here think.

@ronboco 

No, lol.....and I did find a Be tweeter that is not enclosed in a "cage", so I stand corrected.

That being said, I would leave it alone and not mess with it. And Be tweeters are so expensive, I surely wouldn't handle it and/or paint it.

I was not thinking of the tweeter; rather the white drivers :)  I'm hoping to find the best way to change them to black. 

I would trade them in for equivalent or better speakers with black cones. Paint will change one or more characteristics of the cones, magic marker would likely look uneven (every time I tried coloring something with a marker it has looked terrible).
