Full prompt and why it works
Prompt
A wide editorial illustration for the header of a blog post about {{topic}}, for readers of {{publication}}. It shows {{scene}} as the single clear focal point, placed in the right two thirds of the frame. The left third is calm, uncluttered background, so a headline can sit there. The style is flat vector illustration with a subtle paper-like texture, simple geometric shapes and no outlines. The color palette is {{palette}}, with one accent color used only on the focal point. The lighting is soft and even, with gentle shadows that give the shapes depth. Render the headline "{{headline}}" in the left third, in a bold, clean sans-serif typeface, left-aligned on at most two lines, in a dark color that contrasts with the background. Spell it exactly as written; if it is too long to fit on two lines, set it smaller rather than shortening or changing any word. The image should look professional and calm, in the style of a modern editorial magazine. The aspect ratio is 16:9. Leave out any other words, logos, watermarks and recognizable real people.
Variables
- {{topic}}
- What the post is about.
- {{publication}}
- Who reads it, for example "a developer blog" or "a small-business newsletter".
- {{scene}}
- The concrete picture, for example "a paper airplane folded from an invoice, flying over a row of filing cabinets".
- {{palette}}
- Three or four colors, for example "deep navy, cream and soft coral".
- {{headline}}
- The exact words to render. Shorter headlines render more reliably.
Why it works
- Layout. Google's image models want full sentences that describe the scene, and three short paragraphs do that: subject and layout, then style and light, then the text.
- Background facts. Concrete layout instructions (focal point on the right, an empty left third) leave room for the headline instead of hoping the model finds it. If your tool has a size setting, set the same 16:9 ratio there.
- If unsure. The exact-text instruction covers the failure case: if the headline is long, set it smaller rather than rewording it.
