Chalkboard aesthetic — the visual language of artisan hand-lettering on dark board surfaces. COLOR CLIMATE: high-contrast warmth defines the palette. Foreground marks: cream-white to warm ivory as the primary tone, with dusty pastel accents — soft coral, sage, lavender, warm mustard — for secondary decorative elements. Background ground: deep chalkboard green-black or charcoal slate. The dark ground is an active compositional element, not neutral filler. LIGHT ATMOSPHERE: warm overhead ambient at cafe or classroom intensity — the quality of morning light through a cafe window or an evening Edison bulb above a pub specials board. Soft directional quality, revealing surface and dimension without creating harsh contrast. Warm, inviting, crafted. DECORATIVE REGISTER: simple hand-drawn borders of dots, dashes, or double-ruled lines; small illustrative accents (arrows, stars, leaves, dividers); mixed-weight lettering styles on the same surface — all belong to the chalk aesthetic vocabulary and may appear in compositions. When no specific material is defined by the font: default lighting environment — warm overhead ambient, cream-white chalk tones against deep chalkboard green-black board ground, soft and matte in quality. A classroom chalkboard mounted on a painted cinder-block wall, the dark slate surface filling the frame with authentic depth and texture. Warm morning light filters through tall schoolroom windows from the upper left, casting a gentle directional glow across the board surface. The wooden chalk tray at the bottom edge is dusted with residual chalk powder, a subtle eraser smear visible at one corner lending honest classroom authenticity. A hand-drawn star accent and small laurel-leaf dividers flank the text in dusty pastel yellow, echoing a playful civic campaign aesthetic. 'class mayor' occupies the dominant visual zone of the board, the lettering filling approximately 72% of frame width with confident weight. The surrounding cinder-block wall fades into warm amber shadow at the edges, the board's wooden frame catching a soft highlight along its upper rail. An Edison-style overhead classroom fixture contributes a secondary warm glow from above, reinforcing the chalk-on-board materiality — matte, powdery, and tactile throughout.
