Since when is personal preference "factual"?
You're entitled to your opinion, that's all it is.
Rember to stay on topic. This is a debate on the most versatile of colours.
There's a reason NONE of the renders on Apple's website use black as the base colour to pair with all the more colourful bands. It's always silver, gold or starlight.
There is a phrase that's an illuminating simile on this topic: "Anyone can cook."
It's not about just anyone being able to cook, it's about great cooks coming from all walks of life and all backgrounds with wholly different "tastescapes".
Whereas some people will just throw Roquefort in a chocolate fondue, burn it, dip grapefruit in it, and call it cuisine, and you can't convince them it's disgusting.
You can try and pair your shiny black watch with a lavender blue woven band, see what good it does you.
Black simply does not pair well with everything, and no, it's not a matter of opinion or taste. But then Americans also like to drizzle maple syrup on fried chicken waffles, so anything goes.
Meanwhile I have provided an example of a colour that is versatile all along a huge spectrum or colours, finishes and fabrics, with the notable exception of black, for a reason: because black is in a league of its own.
Black goes with cloudy dark colours, burgundys, deep forest greens, midnight blues, smokey purples, earthy mineral natural tones. Black clashes with gold and silver, HARD. That's a fact of life. You can do whatever you want, some people have terrible, tacky taste and like it. But there is such a thing as the science of colour-matching with undertones, warmth, vividness, RGB composition.
I can show you what matches black beautifully.
The Midnight (black) woven band works. Not the others. Denim is pushing it.
The Black and Blue Nike band also works. The Black and red and Green and gray ones would also pass with Black.
The Black sportsband would work, while the stone gray would be pushing it, but pass.
The Ocean, Trail and Alpine lines all work (even the sandy one), except ice blue.
The Black unity ones, obviously.
Sage, Ink, Plum, Blue flame.
Blackberry, Dark taupe, Deep blue, bleu nuit en mer from Hermès.
And as I've said earlier, if you can find RGB-style red green and blues (including the black unity details such as yellow, basically the Jamaican flag), but it will be sporty and summery and youthful, 1990s, even rasta, but never adult, never pro, never versatile.
You can go with solid, vivid colours, even the ones I have rejected from the current selection, but it will never go well as a natural fit, and you'd better pair them as highlights from your outfit, and wear black shoes with the same finish.
For example, I love the Raspberry woven band, which is a bright reddish pink like lipstick. But I don't wear it with an outfit of primary colours. It has to go well with the undertones, so I have very few items I can wear it with.
At one point, the issue isn't just with pairing the right watch colour. If the watch and the band aren't matched, you won't find anything to wear to make it acceptable.
But you could wear the black watch with an ice blue band, provided you're wearing an ice blue costume and black dress shoes with a shiny finish.
Anyone can cook, but not "anyone" CAN cook.
