Get an email header image with the right sale number

About this exercise

You're sending the Copperleaf Home winter sale email and need the header image from Gemini. Get Claude to write one paste-ready prompt, plain text, under 110 words: a prompt paragraph and a last line starting "Avoid:". It must say a wide 3:1 banner, allow only the text "WINTER SALE 25% OFF" (the current discount), name both hex colors, and keep the products to throws and pillows only.

Common mistakes when you ask AI for this

• Using the outdated discount. The brief still says 30% up top, and the AI may use it. Try: Add: "The only text is WINTER SALE 25% OFF."
• Too much text. The AI adds the code and date, which image tools garble. Try: Add: "No other words."
• Showing products that aren't on sale. The AI adds the lamp and rug to make the scene feel complete. Try: Add: "Only throws and pillows. Avoid: rug, lamp, candles."
• Colors by name. The AI says "warm copper tones" without the codes. Try: Add: "Use #B5651D and #F3EDE2."
• Headings and tips. The AI writes a design brief, not a prompt. Try: Add: "Output only the prompt and the Avoid line, plain text."

What a strong prompt includes

• Sets the banner shape
• Gives the exact text
• Gives the hex colors
• Limits the products
• Adds an Avoid line
