+# chalkboard
+
+Black chalkboard background with colorful chalk drawing style
+
+## Design Aesthetic
+
+Classic classroom chalkboard aesthetic with hand-drawn chalk illustrations. Nostalgic educational feel with imperfect, sketchy lines that capture the warmth of traditional teaching. Colorful chalk creates visual hierarchy while maintaining the authentic chalkboard experience.
+
+## Background
+
+- Color: Chalkboard Black (#1A1A1A) or Dark Green-Black (#1C2B1C)
+- Texture: Realistic chalkboard texture with subtle scratches, dust particles, and faint eraser marks
+
+## Typography
+
+### Primary Font (Headlines)
+
+Hand-drawn chalk lettering style. Bold, slightly uneven strokes with visible chalk texture. Imperfect baseline adds authenticity. White or bright colored chalk for emphasis.
+
+### Secondary Font (Body)
+
+Neater chalk handwriting for readability. Consistent sizing with natural variation. Light chalk texture, thinner strokes than headlines.
+
+## Color Palette
+
+| Role | Color | Hex | Usage |
+|------|-------|-----|-------|
+| Background | Chalkboard Black | #1A1A1A | Primary background |
+| Alt Background | Green-Black | #1C2B1C | Traditional green board |
+| Primary Text | Chalk White | #F5F5F5 | Main text, outlines |
+| Accent 1 | Chalk Yellow | #FFE566 | Highlights, emphasis |
+| Accent 2 | Chalk Pink | #FF9999 | Secondary highlights |
+| Accent 3 | Chalk Blue | #66B3FF | Diagrams, links |
+| Accent 4 | Chalk Green | #90EE90 | Success, nature |
+| Accent 5 | Chalk Orange | #FFB366 | Warnings, energy |
