原始 Prompt

Nostalgic crayon-style brand logo that feels warm, human, and instantly memorable.

[ Logo Series - Part 3 ]

Prompt:

{
  "prompt_name": "Crayon Sketch Logo Reveal Template",
  "instructions_for_use": "Replace {{COMPANY_NAME}} with the brand name, or attach the uploaded logo file as a reference image and instruct the model to use its exact silhouette/wordmark shape. Replace {{BRAND_PRIMARY_COLOR}} and {{BRAND_SECONDARY_COLOR}} with that brand's official color hex codes. Nothing else in this prompt should be changed.",

  "canvas": {
    "aspect_ratio": "3:4",
    "resolution": "1536x2048",
    "orientation": "vertical portrait"
  },

  "background": {
    "color": "#FFFFFF",
    "description": "Pure flat solid white background, completely clean and uniform. No paper grain, no cream tone, no texture, no vignette, no shadows on the background itself. Must render as true white #FFFFFF edge to edge.",
    "texture": "none"
  },

  "main_subject": {
    "type": "hand-drawn crayon / oil-pastel sketch interpretation of a brand logo",
    "content": "A loose, expressive, hand-sketched recreation of the {{COMPANY_NAME}} logo (wordmark and/or icon exactly as the real brand logo appears), rendered entirely in thick waxy crayon/oil pastel strokes",
    "placement": "perfectly centered both horizontally and vertically on the canvas, occupying roughly 60%-75% of the canvas width, with balanced equal white space margins on all four sides",
    "line_and_stroke_style": [
      "thick, waxy, semi-transparent crayon strokes layered on top of each other",
      "visible directional hatching/scribble strokes filling in solid shapes (not flat vector fill)",
      "uneven, imperfect hand-drawn outlines with slightly wobbly, organic edges — not geometrically perfect",
      "visible tiny white gaps/specks inside filled areas where crayon didn't fully cover (broken coverage look)",
      "occasional overlapping double-strokes where the hand appears to have gone over an edge twice",
      "small scattered flecks, dots, and light splatter marks of the same pigment scattered loosely around the main shape, mimicking dry pastel dust/crumbs",
      "a few faint, barely-visible construction/guide strokes near the top of the drawing, as if lightly sketched before the final strokes",
      "strokes sit flat on the white background with no drop shadow"
    ],
    "color_rule": "Use ONLY the official brand colors of {{COMPANY_NAME}} (primary color {{BRAND_PRIMARY_COLOR}} and secondary color {{BRAND_SECONDARY_COLOR}} if the logo has more than one color). Do not invent new colors. If the logo is monochrome (black/white), render the sketch in a single dark charcoal/black crayon tone instead of full color.",
    "accuracy_rule": "The overall shape, proportions, and letterforms must be clearly recognizable as the real {{COMPANY_NAME}} logo, just filtered through a loose hand-drawn crayon texture — not abstracted beyond recognition."
  },

  "elements_to_exclude": [
    "NO text anywhere on the canvas — no handle/username, no style badge, no watermark icon, no captions, nothing in the top-left, top-right, bottom-left, or bottom-right corners",
    "NO logo icon overlays, NO UI chrome, NO badges, NO pills, NO small circular avatars",
    "DO NOT include the circular badge showing the clean/official vector version of the logo — it must be completely removed",
    "no cream, beige, or textured paper background — must be pure #FFFFFF",
    "no photorealistic rendering, no 3D, no gradients on the crayon strokes themselves",
    "no drop shadows cast onto the white background by the sketch",
    "the canvas must contain ONLY the crayon-sketch logo artwork and nothing else — a completely clean empty white field around it"
  ],

  "overall_mood": "playful, artisanal, nostalgic 'kid-with-a-crayon' recreation of a polished corporate logo, isolated on a crisp clean minimal white canvas with zero UI or text distractions",
