In 1935 Eastman Kodak shipped Kodachrome, the first commercially successful color film, and with it the loudest package on Earth: a chrome-yellow box, a red-and-black wordmark, and 35mm sprocket edges running down every margin. The yellow means color itself — open the box and the world turns saturated.

This is an industrial system, proud of its engineering. Sprocket strips frame content like frames of a filmstrip; ISO/ASA numerals read like the stamping on a canister; photos sit inside white slide-mount borders. High-contrast, warm, unmistakably American — a Kodachrome slide held up to a lightbox.
