A few heavy strokes of black ink, pools of mineral colour soaking into raw paper, and a lot of nothing. Malachite green, azurite blue and a fleck or two of cinnabar red bleed wet-into-wet into soft clouds, the brush runs dry at the end of each stroke, and the bare paper is left to be the light. Fine line only turns up where something small needs it. It's Chinese ink painting at its most economical: say as much as possible with as few marks as you can.
The two painters pull in opposite directions, and that's the point. Zhang's colour is loose and accidental; Xu's black is deliberate and placed. The prompt lets the colour spread and keeps the ink sparing, and the closing line, bare paper left as light, stops the whole thing from filling in.
It's the second style in the collection to borrow Zhang's splashed colour. #696 Tidemark Gouache Dropout pushes it into hard tide-line edges and Art Deco stencilling. This one keeps it where it came from, on soft paper next to ink. Its nearest neighbour by look is #475 Stained Translucent Reverie, which also has a walker between bare trees on a wet path, but that's warm Western watercolour, amber and teal filling the page. This one is cooler, emptier and inked.




The other three models got the plain original prompt, artist names and all, with the collection's usual haiku as the subject. Flux needed a nudge: its first try lost the subject entirely and came back as pure abstract pattern, just washes and flecks with no figure or street, so the canonical was re-rolled with "woman walks away" added after the haiku. That's subject steering, not style, so it isn't part of the prompt above.
It suits anything with space around it: a single figure, a path, a bird on a branch, mountains in mist. A busy scene fights it, because the style wants most of the paper empty. Be plain about the subject, though: the prompt is so much about marks and paper that Flux happily paints only those, so name the figure directly. Hosted models drew it fine from the original prompt here. If one balks at the names, the model-neutral version swaps them for "Chinese splashed-colour painting" and "modern Chinese academic ink painting", and the effect-only version describes just the pooled washes, the loaded stroke and the paper. If a model writes the subject into the picture and you don't want it, give it a literal subject instead of the haiku.
