Prompt Writing Rules
Rules for generating high-quality image generation prompts. Apply these when writing the final prompt in Step 5.
1. Visual Precision
Always describe:
- Background texture (e.g., off-white aged paper, black halftone shadows, light gray grid texture)
- Font style (e.g., handwritten, serif print, colorful block-lettering, monospace technical)
Omitting these causes the image model to make arbitrary choices that undermine the intended aesthetic.
2. Color Avoidance
Never use hexadecimal color codes (#RRGGBB format). Use specific color names instead.
| Instead of | Use |
|---|---|
#FF6B6B |
coral red |
#2D3748 |
deep slate gray |
#F6E05E |
warm yellow |
#68D391 |
sage green |
3. Text Citation
All copy intended to appear as text in the image must be enclosed in "double quotes".
- Correct: a bold label reading
"Step 1: Define the Problem" - Incorrect: a bold label reading Step 1: Define the Problem
This lets the image model distinguish between descriptive instructions and literal text to render.
4. Arrow Minimalism
Minimize the use of arrows. Prefer spatial proximity to imply flow and connection.
When arrows are necessary:
- Specify exact start point and end point (e.g., "an arrow from the 'Input' box pointing to the 'Process' box")
- Never use vague orientations like "a horizontal arrow" or "a vertical arrow"
5. Semantic Correspondence
Every icon, illustration, or decorative element must correspond semantically to the adjacent text content. Avoid generic decorative elements that could apply to any topic.
6. Punctuation Hygiene
Never use quotation marks when describing:
- Style (e.g., write: flat design aesthetic — not: "flat design" aesthetic)
- Layout structure (e.g., write: three-column grid — not: "three-column grid")
- Colors or textures
- Moods or feelings
Quotation marks are reserved exclusively for Rule 3: Text Citation.
7. Step Granularity
If the content contains stages, steps, or a sequence:
- Detail every single step individually
- Never merge or compress multiple steps into one
- Each step gets its own visual element and label
8. Data & Encoding
All hard data from the source must be:
- Preserved verbatim — no paraphrasing of numbers, dates, or proper nouns
- Presented in a visually distinct format: bold text, labeled callout boxes, sticky notes, or data badges
