gold
Six directions with no roof, gable or house shape anywhere. Elegance here comes from restraint, a real measure and one drawn detail, rather than from depicting the product. Rendered in gold; a flat production colourway is cut alongside every one.
Two Bs mirrored on one shared spine.
Codex ranked this first and called it the only one with a plausible route to recognition beyond a serif B in gold. It also caught that the two stems were standing side by side with a slot down the middle, so the mirror axis now runs through the centre of the stem and the letters share one spine by construction.
Solid gold field, letter truly knocked out.
The practical badge: one solid silhouette, so it is the best small size performer here. Codex caught that the light version drew a black B instead of revealing the substrate, so it is now a real knockout and the background shows through the letter, including over a photograph.
No letter at all. Type, a measure, and stop.
Codex answered the question I was unsure about plainly: reputation is not a prerequisite for a wordmark, and a new firm benefits from putting its actual name in front of people. It also flagged the B above the wordmark as duplicating the initial already in BISCHOFF, so the device is now rules and one small lozenge, with no redundant letter.
