Soft 3D / Claymorphism Style System

Design Intent

Create a minimalist professional presentation style with soft matte 3D geometric shapes floating in corners. The deck should feel airy, modern, sophisticated, and UI-polished. It should not feel like a children's clay illustration or a generic pastel template.

Palette

Role	HEX	Usage
Warm beige	`#FDF5E6`	Main background
Sage green	`#B2AC88`	Primary accent, 3D shape base, section markers
Morandi warm pink	`#DBADAD`	Secondary accent, soft 3D shape, warm emphasis
Charcoal	`#333333`	Main text
Secondary text	`#6B6B6B`	Body support, captions
Soft divider	`#E7DAC8`	Hairlines, panel borders
Highlight surface	`#FFF9EF`	Soft cards/panels
Shadow tone	`#C8BBA8`	Shadow approximation in SVG/PPT

Rules:

Use beige as the dominant surface.
Use sage and warm pink as accents, not equal full-page backgrounds.
Do not introduce saturated purple, blue, neon green, or strong gradients.
Keep text charcoal; avoid pure black.

3D Material Rules

Claymorphism here means soft matte depth, not realistic 3D rendering.

Use:

Rounded spheres, pills, capsules, soft cubes, rings, torus-like arcs, and abstract blobs.
Pastel fills with subtle highlight and shadow.
Corner placement: top-right, bottom-left, or side gutters.
Low-contrast depth to frame content.

Avoid:

Large central 3D objects on every page.
Plastic shine, metallic reflections, or harsh perspective.
Dense stacks of shapes.
Shapes behind small text.

SVG/PPT approximation:

Use circles, ellipses, rounded rectangles, and paths.
Create depth with 2-3 layered shapes: base fill, low-opacity highlight, soft offset shadow.
Use opacity attributes rather than rgba().
If using ppt-master, avoid filters unless confirmed safe; use simple layered geometry instead.

Typography

PPT-safe default:

Title: Arial, Microsoft YaHei, sans-serif
Body: Microsoft YaHei, PingFang SC, Arial, sans-serif
Label/code: Consolas, Courier New, monospace

Direction:

Use clean, rounded-feeling sans typography.
Titles should be confident but not oversized.
Body copy should be quiet and readable.
Use monospace only for labels, page numbers, and small technical tags.

Suggested sizes for 16:9:

Cover title: 56-76 px.
Page title: 34-42 px.
Subtitle: 22-26 px.
Body: 18-21 px.
Caption/metadata: 11-14 px.

Layout and Spacing

Use generous whitespace and stable grid alignment.
Prefer two-column layouts, hero object + text, or soft panel groups.
Cards may be used, but should be soft and purposeful.
Keep border radius moderate: 12-24 px for panels, larger for decorative shapes.
Use soft shadows sparingly and consistently.

Icon Strategy

For ppt-master, prefer tabler-outline or simple custom line icons.

Icons should be thin, charcoal or sage.
Avoid filled icon badges unless they are very subtle.
Use at most 1-3 icons per slide.

Imagery

Best image types:

Product UI screenshots
Clean workspace details
Soft product photography
Minimal abstract renderings

Treatment:

Use images inside soft rounded rectangles or edge-aligned frames.
Pair with 3D corner accents, not full decorative backgrounds.
Avoid busy lifestyle photos and overly colorful stock imagery.
