Approach: conceptual metaphor. Palette: D, bold color field.

A single AA-style cylindrical battery stands upright, fully charged, on a seamless saturated mustard-yellow backdrop. Beside it sits a matching, untouched, slightly dusty glass jar of marbles, so the charge shows no visible link to any result. More precisely, a bright tomato-red extension cord plugs into the battery's top. Its other end curls away unconnected, lying on the floor beside an unlit incandescent bulb. A small electric green LED glows on the battery's side as the only green accent. Camera: low three-quarter angle, 50mm lens, shallow depth of field, with the bulb softly blurred in the foreground. Lighting: hard, clean studio key light from the upper left, with crisp shadows falling to the right on the yellow surface. Mood: puzzled, wry, a full power source that fails to light anything.

**Approach: Macro science. Palette: D, bold color field (deep magenta).**

An extreme close-up photograph of a real spermidine crystalline powder deposit, pale ivory needle-like crystals fanning out in clustered rosettes, shot with a macro lens at a shallow 30-degree overhead angle. The crystals sit on a smooth, saturated magenta acrylic surface that fills the whole frame. Soft, directional studio light from the upper left creates crisp highlights along the crystal edges, translucent glints inside the needles, and short, clean shadows on the magenta. Depth of field is razor-thin, so the front cluster is sharp and the background dissolves into creamy pink bokeh. One tiny crystal tip catches a faint electric green reflection. The mood is precise, curious and quietly skeptical, like a specimen under evaluation. No text, no labels, no hands.
