Approach: human outcome. Palette: natural.

Close, low-angle shot of an older adult's bare lower leg and bare feet resting on crisp white hospital bed linen, with a soft, out-of-focus window in the background. The camera sits at mattress level and looks along the calf toward the ankle. Face is not visible. A small ultrasound probe coated in clear gel presses against the back of the knee. The operator's gloved hand enters from the frame edge. Soft overcast daylight from the window gives skin tones a warm, realistic look. Around the bed, a sprig of fresh rosemary and a few purple-green ashwagandha leaves sit on a wooden bedside tray. The leaves provide plant-green accents, along with one small electric green sensor light on a monitor. Palette: natural greens, wood browns and warm skin. Mood: quiet, careful and hopeful.

**Approach:** Conceptual metaphor, in a bold color field palette (D).

A single ripe pomegranate, split open, on a saturated teal backdrop. It is the natural source of urolithin A's precursors. The camera sits at a slightly low three-quarter angle, close enough to show glossy, translucent arils. On the left half, the arils sit dull and tightly packed. On the right, a few arils hold a faint electric green glow, as if lit from within, hinting at a selective response in one place and not another. Behind the fruit, a thin copper wire runs across the frame and is unbroken on one side and fraying on the other, standing for arteries versus brain vessels. Soft, directional studio light from the upper left casts crisp shadows. Mood: curious, restrained, quietly hopeful. No text anywhere.
