“Marcus”是使用 FontVibe AI 创作的3D 立体粗体文字效果。厚重的方块大写字母带深度挤出，每个字母一种亮面糖果色，顶光让高光滚过圆润边角，彩色倒影落在地面上。

Create a finished horizontal desk name sign, 3:2 aspect ratio. Render exactly one line of text, spelled and cased exactly: “Marcus”. Make the name the clear focal point, centered and large, occupying about 78% of the canvas width. Use chunky, heavy block letterforms with broad strokes, simple geometry, tight but readable spacing, and hard, un-beveled edges. Each adjacent letter has a different vivid saturated hue: M cherry red, a electric blue, r sunshine yellow, c lime green, u hot orange, s violet. Give every front face an ultra-glossy hard-candy lacquer finish with natural specular highlights that shift from bright reflections to saturated color. Extrude each letter uniformly to about 55% of its height; make the sides a darker shade of that letter’s face color with crisp face-to-side boundaries. The letters stand on a slim, low dark charcoal acrylic desk-sign base, with no writing on the base. Show the base clearly beneath the name. Minimal dark studio floor and background, faint floor reflections only. Strong directional key light from upper left, crisp cast shadows extending diagonally at 45 degrees with shadow depth around 45% of letter height. Nearly frontal camera at a slight low angle, clean product-render composition, sharp focus, high contrast, physically plausible glossy reflections. No extra text, icons, people, clutter, gradients, or decorative props.
