A wall of RGB light in an electronics market: a narrow stall in a crowded Korean electronics arcade where the entire back wall is a grid of hundreds of glowing PC fans, LED strips and translucent keyboards all cycling the same rainbow gradient, red through orange, yellow, green, cyan, blue and violet sweeping diagonally across the wall. Coiled cables and stacks of plain unbranded boxes on the counter, a shopkeeper silhouetted small at the counter. Everything else dark so the light dominates. Maximum saturation. No text, no letters, no logos.
