I don’t accept gray and beige as real colors. Give me something like purple, violet, lime green, OD green, orange, aqua blue, or hot pink.
The green used on the Wurkkos HD20 would be fine.
The champagne looks similar to a redux of Sofirn’s old “pale gold.” It’s a nice color. All of them look good; anything but Boring Black.
But if we’re talking aesthetics, trying to apply the Hot warning symbol atop the grooves looks janky, and I’m not fond of the polarity marking, which will offend those with OCD sensibilities when it inevitably doesn’t align nicely with the rest like in the pretty promo pictures.
Final item on the wish list would be a new version of the FC11 with a regulated driver. Oh so close to ticking all the boxes, except that one.
