All of them. It's not a question of assigning a "value" to each button to determine which is more important to be visible. Those choices will vary with user anyway. Some users like the band buttons on the KPA500 to change bands on their K-Line.
When operating, I can distract myself from DXing or contesting for a few seconds to stare at the front panel of the KPA500 and find the button I'm looking for. I'd rather be able to spot the desired button out of the corner of my eye without losing operation focus. Contrasting button colors support that use case.

John KK9A From: Ed Muns ed at w0yk.com Sat Mar 18 14:25:12 EDT 2017 Based on the excellent KPA500 design, augmented by user experience, and the added comments to Eric's question below, I'm confident Elecraft can define another great product if they so choose. My request is that the button colors be more functional than they are on the KPA500. "Black on Black" is aesthetically very cool in a well-lit environment, but functionally very poor in most actual operational environments. Some of us have replaced the KPA500 button caps with gray and other colors like on the K3, so we can find the buttons more readily. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
