# 12 Duotone Split - Duotone Split

## Style Overview

Charcoal and terracotta dual-color panels split the canvas in different proportions, morph produces "shifting canvas" effect.

- **Scene**: Brand launches, architectural design, high-end presentations
- **Mood**: Bold, architectural feel, high-end, minimalist
- **Tone**: Dual-color contrast (deep dark + warm color), white dividers

## Design Techniques

- **Dual-panel split**: Two large rect (!!panel-dark + !!panel-warm) cover entire canvas, split in different proportions
- **White divider line**: 0.3cm wide white rect as precise divider between two panels
- **Split proportion changes**: S1 left-right 50/50 → S2 top-bottom 70/30 → S3 left-right 30/70 → S4 diagonal rotation → S5 top-bottom 80/20
- **Morph choreography**: Massive changes in panel size and position produce "shifting canvas" effect, divider line follows movement
- **Rotation variation**: S4 panels rotated -8 degrees, breaking orthogonal layout for added dynamism
- **Restrained decoration**: Only 2 semi-transparent dots + 1 ultra-thin line, maintaining minimalism
