“T”是使用 FontVibe AI 创作的水彩文字效果。衬线大写字母填满透明水彩晕染和小花枝，白纸透出光亮，写在毛边冷压水彩纸上，旁边是调色盘。

Create a finished square lettermark logo on a single sheet of fine cold-press watercolor paper, viewed straight-on, no mockup. Center one large, custom hand-painted uppercase letter “T” as the sole rendered text, occupying 58% of the canvas height. The T has a wide, slightly arched horizontal brush crossbar and one tapered vertical stem; its silhouette is balanced, distinctive, and immediately legible at small size. Paint the letter in layered transparent cobalt, cerulean, sap green, and a restrained rose-madder trace: pale luminous centers where unpainted white paper shows through; darker pigment pooled along stroke boundaries; tiny bare-paper tooth flecks; granulated pigment settled into the paper grain; diffuse wet-into-wet cauliflower blooms at the crossbar-to-stem junction; intermittent crisp dry-paper brush edges and a few controlled dry-brush breaks. No opaque paint, no digital gradients, no printed font, no shadowed 3D effect. Leave generous clean white negative space around the T. Frame it with only four sparse botanical watercolor details: a small olive-green stem with two leaves at upper left, a soft rose-madder bud at upper right, a low cerulean leaf sprig at lower left, and a tiny raw-sienna seed cluster at lower right; keep all botanicals outside the clearspace of the lettermark. Soft even north-window light, bright white paper as the highest value, subtle cool contact shadow around the faint deckled paper edge, gallery-flat composition, realistic watercolor pigment behavior, high-resolution scanned fine-art stationery.
