Consistent visuals matter more than perfect ones. The trick is to write your brand down once and paste it into every prompt, instead of rewriting your style each time. Tools are adding this natively: Google says Gemini’s new small-business tools can keep an uploaded brand style, but the same method works in any image tool.
Step 1: write a brand block
Keep it under 60 words and reuse it unchanged.
Brand block: warm and friendly, soft natural light, cream background, dusty-green and terracotta accents, rounded sans-serif headings, plenty of empty space, no clutter, no stock-photo smiles.Step 2: add the job
Put the job first, then the brand block, then the format.
- Product launch post
Square social post announcing a new ceramic mug. Show the mug on a wooden table with morning light. Leave the top third empty for a headline. [Brand block] - Seasonal campaign
Banner for an autumn sale at a small bakery: warm pastries, falling leaves, flat-lay view, wide 16:9 format. [Brand block] - Story background
Vertical 9:16 background texture in our palette with a soft paper grain and an empty centre for text. [Brand block] - Product on a clean backdrop
Our linen tote bag on a pale stone surface, soft shadow, studio look, no props. [Brand block] - Icon set
Four simple line icons (delivery, gift, heart, clock) in terracotta on cream, equal stroke width. [Brand block]
Review checklist
- Do colours match your palette? Compare against your real brand kit.
- Is there readable text? Check spelling, or add the text yourself in your design tool. See best AI for text in images.
- Does it look like your last five posts? If not, tighten the brand block.
- Is it free of real people’s likenesses and other brands’ logos?
