Generate a matching set of carousel images that share one visual system
Produces a full run of social-carousel slide images that share one deliberate color, typography, and layout system across every slide — anchored to a written style system rather than each slide being generated as an unrelated image that happens to share a topic.
The prompt
Ready to copy — highlighted parts are example details you can swap.
You are generating a full set of images for a social-media carousel post. Every slide in this set must look like it belongs to one designed system — not like separate images that happen to cover related topics. CAROUSEL TOPIC AND SLIDE COUNT 6 slides explaining "5 signs your invoice process needs automation," plus a closing slide with a call to action. SHARED VISUAL SYSTEM flat, minimal line-art icons paired with short bold headline text at the top and a one-line supporting sentence below. This system applies identically to every slide in the set: same illustration or photographic treatment, same overall composition logic (where headline text sits, where supporting visuals sit), same visual weight and density from slide to slide, so a viewer swiping through experiences one continuous design language, not a new visual decision on every slide. COLOR AND TYPOGRAPHY SYSTEM deep navy background, warm coral accent color for icons and highlights, off-white text, a bold rounded sans-serif for headlines. Use this exact palette and type treatment on every slide with no exceptions — if one slide's content naturally suggests a different accent color, resist that pull and stay within the defined system; visual consistency across the set matters more than any single slide's individual optimization. PER-SLIDE CONTENT 1. Title slide: "5 Signs Your Invoice Process Needs Automation." 2-6: one sign each, with a matching simple icon. 7. Closing slide: "Try it free — link in bio.". Render each slide's specific content within the shared system defined above — the content changes slide to slide, the visual language around it does not. SLIDE NUMBERING AND CONTINUITY Include a small, consistent slide-position indicator (a number, a progress dot pattern, or similar) in the same location on every slide, styled consistently with the rest of the system, so the set reads clearly as an ordered sequence rather than a disconnected group of images. FRAMING Render every slide at 4:5, sized for Instagram carousel posts, with consistent margins and safe-zone spacing across the whole set — nothing critical (headline text, key visual elements) should sit close enough to any edge that it would risk being cropped differently by different platforms' carousel viewers. CONSISTENCY CHECK Before finalizing the set, compare every slide against the first one you generated — check that the color palette, typography treatment, and layout logic haven't drifted by the last slide compared to the first, since a carousel where slide seven subtly departs from slide one's established system undermines the whole set's cohesion even if slide seven looks fine in isolation. OUTPUT The complete numbered set of slide images, each following the same visual system, ready to upload as one carousel post in order.

Why this works
Defining the color and typography system as a fixed constraint the model must hold even when a specific slide's content "wants" a different accent color addresses a real tension in multi-image generation: each individual slide, generated with only its own content in mind, will tend to drift toward whatever visual choice looks best for that one slide in isolation, and across a seven-slide set that individually-optimized drift compounds into a carousel that doesn't actually look like one designed piece, which defeats the entire point of a carousel format that depends on visual continuity to keep someone swiping through it. Second, the consistency check comparing every later slide back to the first one specifically — rather than just to the general style description — matters because Nano Banana's session memory of an established visual system tends to degrade gradually rather than fail all at once, the same drift pattern that shows up in multi-scene character consistency work, so a carousel's sixth or seventh slide is the one most at risk of quietly departing from the system established on slide one, and that's precisely the failure a viewer swiping start-to-finish is most likely to actually notice, since they're comparing each new slide against the visual memory of the ones before it in real time. Third, requiring a consistent slide-position indicator styled as part of the same system, rather than treated as an afterthought, matters because a carousel's format-specific advantage over a single image is its implied sequence — a viewer expects to swipe through an ordered set — and a set of otherwise-consistent slides that lacks any visual cue about where they are in that sequence loses part of what makes the carousel format work as a content structure in the first place, even before considering the visual-consistency question at all.
