HIGH-GRANULARITY VISUAL INVENTORY

Subject(s)
- Count: 1 graphic poster / event announcement design
- Format: square 1:1 social post with rounded corners

Background
- Primary background: pink field with a light grid pattern (thin white grid lines)
- Subtle soft gradient vignette toward corners
- A solid teal/green vertical strip on the far right edge (like a color block)

Main shape
- Large teal/green circle centered slightly above the middle
- Circle overlaps the grid background and acts as the main text container

Typography / text layout
- Top arc text inside/over the circle: “KAF POP-UP STORE” in white, curved along the top of the circle
- Large Japanese title text in white spans across the circle and slightly extends beyond it (very large serif-like Japanese font)
- A row of small rounded white capsules/dots with Japanese characters inside (pink/red characters) across the middle
- Lower center text: “at Shibuya Sakura Stage” in white
- Smaller line below: “SHIBUYA SIDE 4F ‘404 Not Found’” in white

Info blocks (bottom)
- Two horizontal info modules near the bottom:
  - Left module: teal header label (Japanese) above a white rectangle containing date range (Japanese numerals) “2025年4月5日(土) — 13日(日)”
  - Right module: teal header label (Japanese) above a white rectangle containing “10:00 — 20:00”
  - Small fine print under the right module (start/end day hours)

Brand marks
- Small white logos/marks centered at the bottom margin

Style
- Flat vector poster, crisp edges, clean alignment, strong color blocking

Color palette (approx)
- Pink background: #d98aa3 to #e2a0b4
- Teal/green circle and labels: #0aa38f to #0aa590
- White text and boxes: pure white
- Accent text in capsules: muted red/pink

MASTER PROMPT (English)

[Goal]
Create a square 1:1 flat vector event announcement poster with a pink grid background and a large teal circle containing bold Japanese title typography.

[Layout]
Pink background with thin white grid lines, rounded-corner canvas, and a vertical teal strip on the far right edge. Place a large teal circle centered slightly above mid-frame. Put curved white text along the top arc of the circle reading “KAF POP-UP STORE”. Overlay very large white Japanese title text across the circle (spilling slightly beyond). Add a row of small rounded white capsules with pink/red Japanese characters across the center.

[Event info]
Add centered white lines: “at Shibuya Sakura Stage” and “SHIBUYA SIDE 4F ‘404 Not Found’”. At the bottom, place two modules: left shows the date range (Japanese format), right shows business hours “10:00 — 20:00”, each with a teal header label and a white content box.

[Style]
Flat vector, crisp alignment, high legibility, minimal decoration, no 3D.

[Detail constraints]
Keep the pink grid + teal circle color scheme; keep the two bottom info blocks; keep the curved header text.

NEGATIVE PROMPT
Photorealism, 3D, heavy gradients, messy texture, illegible text, extra icons, skewed perspective, watermark.

SUGGESTED PARAMETERS (starting points)
- Aspect ratio: 1:1
- Resolution: 1024x1024 or 1080x1080
- Steps: 25–40
- CFG / guidance: 4–7
- Sampler: DPM++ 2M Karras (SDXL) / high-quality default (FLUX)
- Seed: 250310

DELTA PROMPT STRATEGY (top drift risks → corrective micro-prompts)
1) Grid disappears → “pink background with thin white grid lines”
2) Circle off-center → “large teal circle centered slightly above middle”
3) Typography too small → “very large Japanese title text dominating the center”
4) Loses curved header → “curved arc text ‘KAF POP-UP STORE’ along top of circle”
5) Info blocks missing → “two bottom info modules: date range left, hours right”
6) Adds extra decoration → “minimal flat vector poster, clean alignment”
7) Colors drift → “pink + teal + white only, controlled palette”
8) Perspective tilt → “front-on flat layout”
9) Text unreadable → “high legibility, bold type, clear spacing”
10) Right teal strip missing → “vertical teal strip on far right edge”

How virtual_kaf Announced This KAF Pop-Up Store at Shibuya Sakura Stage

This announcement design is a great pattern for creators who need to communicate event details fast. It’s not trying to be complicated. It uses a single dominant shape (the circle), a strict two-color system (pink + teal), and a clear information layout at the bottom. That’s why it reads instantly in a feed.

When you’re promoting a pop-up store, you’re competing with everything else on someone’s screen. The design job is to make the viewer understand: what it is, where it is, and when it is—in one second.

Why it spreads: strong geometry creates “brand memory”

Circles are underrated for announcements. They act like a spotlight: your title sits inside a shape that’s impossible to ignore, and your eye doesn’t get lost in the background. The grid texture adds just enough structure to feel designed, but it stays quiet so the headline stays dominant.

The real growth lesson is information hierarchy. The title is huge. The location is centered. The date and hours are locked into two neat blocks. That makes the post screenshot-friendly—exactly what you want for event promotion.

Signal table

Signal	Evidence (from this image)	Mechanism	Replication Action
Headline dominance	Massive title text across the central circle	Instant comprehension at thumbnail size	Make the headline 60–70% of the visual weight
Two-color discipline	Pink background + teal circle + white type	Feels branded and cohesive	Pick 2 base colors and refuse extra accents
Screenshot-friendly details	Date and hours in two bottom info blocks	People can save and reference quickly	Put date/time in fixed blocks, not buried in caption
Soft structure texture	Light grid pattern under the main shape	Adds design credibility without clutter	Use one subtle background pattern at low contrast

Use cases & transfers

Best-fit scenarios

Pop-up stores: location + dates + hours in one shareable card.
Tour stops: swap the bottom blocks for city + venue + door time.
Release events: use the circle for the title and keep details in fixed modules.
Community meetups: clean layout works even with small teams and fast timelines.

Not ideal

Complex schedules: if you have many sessions, use a timetable grid instead.
Overly decorative branding: this system is minimal by design—don’t overload it.
Text-heavy content: keep copy short; link to details elsewhere.

Transfers (3 recipes)

Recipe 1: Shape swap
- Keep: two-color palette, clear bottom info blocks
- Change: {shape} = circle / oval / rounded rectangle
- Slot template: “two-color event poster with {shape} headline container and two info blocks (date + hours)”
Recipe 2: Category color system
- Keep: background pattern + headline container
- Change: {colors} = spring pastel / monochrome + one accent / night neon
- Slot template: “flat vector poster, {colors}, high legibility, strict hierarchy”
Recipe 3: Detail modules
- Keep: the big title system
- Change: bottom blocks become {venue + doors} / {ticket URL + time} / {city + date}
- Slot template: “headline-first poster with modular detail blocks for {detail fields}”

Aesthetic read: geometry is doing the hierarchy

The circle isn’t just decoration. It’s a hierarchy device. It creates a focal area where the title can be huge without looking chaotic. The grid background adds order. The bottom blocks create a stable “footer” that anchors the details. Together, it feels official and repeatable—two qualities that make announcement posts easy to share.

If you want to level this up, focus on spacing: equal padding, aligned edges, and consistent font weights. That’s what makes minimal designs feel premium.

“flat vector, crisp alignment, no 3D”	Official poster feel	“slight paper texture”, “rounded chips”, “thin outlines”
