What this prompt does
This prompt casts the AI as a senior art director and makes it write a copy-ready Midjourney prompt for a premium SaaS homepage hero illustration that reads in both light and dark mode. You provide the [product_name], [product_category], [subject], and [palette]. It returns a finished Midjourney prompt for a modern-editorial hero, composition notes (depth via soft glow, layered geometry, a clear focal point), explicit palette usage with one dominant colour and one accent, a negative prompt, the correct flags, and two variation lines that change only mood or density.
The structure works because it locks the brand-defining choices before iterating on the look. By fixing [palette] to one dominant colour and one accent and appending --v 6 --ar 16:9 --style raw, the prompt keeps every render on-brand and correctly sized. [subject] sets what the hero depicts, while the negative prompt fights stock-photo cliches, over-rendered detail, and clutter. The two variation lines let you explore mood without breaking the established palette or aspect ratio.
When to use it
- You need a homepage hero illustration that a buyer judges in the first second.
- You want an abstract, premium hero rather than a literal UI screenshot that looks cheap.
- You need the image to read cleanly in both light and dark mode.
- You want a locked palette and aspect ratio so a series stays on-brand.
- You need a negative prompt to keep stock-photo cliches and clutter out.
- You want two variation lines to explore mood without redesigning from scratch.
Example output
You get a copy-ready Midjourney prompt in a fenced block — describing a premium, modern-editorial hero with layered geometry, soft glow for depth, a clear focal point, explicit one-dominant-one-accent palette use, a negative prompt, and the flags --v 6 --ar 16:9 --style raw — followed by two variation lines that change only mood or density while keeping the brand intact.
Pro tips
- Lock
[palette]to one dominant colour and one accent first, then iterate only on[subject]— changing both at once muddies the brand read. - Keep
[subject]abstract for a hero; literal UI screenshots usually look cheap, so save real product shots for further down the page. - Trust the
--ar 16:9flag for a standard hero, and only change it if your layout genuinely needs a different ratio. - Use the negative prompt as written to keep out stock-photo cliches and over-rendered clutter, adding terms only as new artefacts appear.
- Run the two variation lines to compare mood and density before committing, since the first grid is rarely the final pick.
- Check the result in both light and dark backgrounds, since the prompt is built to read in both and you want to verify it does.
