+# 10 Candy Stripe — Rainbow Candy Stripes
+
+## Style Overview
+
+Six full-width rainbow stripes slide, stretch, and gather across pages on white background, creating festive joyful atmosphere.
+
+- **Scene**: Celebrations, festivals, children's education, creative marketing
+- **Mood**: Joyful, lively, festive, rainbow
+- **Tone**: White base, six-color rainbow accents
+
+## Color Palette
+
+| Name         | Hex     | Usage            |
+| ------------ | ------- | ---------------- |
+| Pure White   | #FFFFFF | Page background  |
+| Candy Red    | #FF5252 | Rainbow stripe 1 |
+| Orange       | #FF7B39 | Rainbow stripe 2 |
+| Lemon Yellow | #FFD740 | Rainbow stripe 3 |
+| Mint Green   | #69F0AE | Rainbow stripe 4 |
+| Sky Blue     | #40C4FF | Rainbow stripe 5 |
+| Violet       | #7C4DFF | Rainbow stripe 6 |
+| Title Black  | #1A1A1A | Title text       |
+| Body Gray    | #555555 | Body text        |
+
+## Typography
+
+| Element       | Font           | Size    |
+| ------------- | -------------- | ------- |
+| Main Title    | Segoe UI Black | 54-64pt |
+| Data Numbers  | Segoe UI Black | 48-72pt |
+| Column Title  | Segoe UI Black | 28-40pt |
+| Body/Subtitle | Segoe UI       | 16-28pt |
+
+## Design Techniques
+
+- **Full-width rainbow stripes**: 6 full-width rect (width=34cm), creating visual rhythm through y position and height changes only
+- **Vertical sliding**: Stripes slide up and down between pages, morph produces smooth vertical movement
+- **Stretch variation**: Stripe height changes from 2cm (evenly spread) to 0.3cm (compressed into thin lines) to 8cm (expanded into large color block backgrounds)
+- **Opacity adjustment**: 0.12 (faded as card background) to 0.85 (normal display) to 1.0 (deepened when compressed)
+- **Functional transformation**: S1 evenly distributed → S2 compressed into top color bar → S3 becomes three-column card backgrounds → S4 blue expands as data background → S5 gathers into bottom gradient color bar
