"Okay, we COULD just label the ports with regular high color contrast paint. Say, white paint on a black background or black paint on a white background. But that would be TOO EASY and the panel would then really 'pop' against our otherwise monolithic clean design. Which would be distracting."

"But during actual use the ports are going to be on the BACK of the device (so you won't see it) and will have random stuff plugged into some of the ports, which ALSO would disturb the pure clean lines of the thing, so who cares?"

"No, no, we've got to label this thing with black labels on a black background, so it blends in."

"How will people be able to see the labels?"

"Easy. We'll add LED backlighting!"

"How will people TURN ON the LED backlighting, without the button to do THAT destroying our perfect design?"

"Simple - there's no button for it - you just move the machine to turn on the backlight!"

"What if you want the backlight to STAY on for a while, longer than the default?"

"Just keep shaking the machine. Or duct-tape a vibrator to it."

"That's PERFECT!"
