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 dark chalkboard board within a wooden frame, warm amber overhead light. Generous vertical spacing between text tiers. Top: "THE TGS No Nonsense fuel guide" as the headline, centered, filling 70% of frame width, slightly larger scale. Below: two column-style equation blocks, each centered, filling 55% of frame width, with visible internal line spacing — first block: "Diesel = MGO" / "Gasoil = MGO" / "ULSD = MGO" / "ADO = MGO" / "DMA = MGO" stacked as five lines; a visual gap separates the second block: "VLSFO = HFO" / "RMG = HFO" / "RME = HFO" / "Residual Fuel Oil = HFO" / "Sticky stuff = HFO" / "380 = HFO" / "180 = HFO" stacked as seven lines; a second visual gap separates the closing block: "Fuel = HFO or MGo" / "Gasoiline = Not fuel" / "Suplhur = Also not fuel" stacked as three lines, centered, filling 50% of frame width, slightly smaller scale as a footnote tier. 16:9 horizontal format.
