The roundel legend

Every color scheme site faces the same layout problem: how do you present eight colors so that a stranger can hold them in their head? A flat row of hex codes is a spreadsheet. Vertical bars look like a paint catalogue. Both formats say what the colors are and nothing about how to remember them.

The answer came from the subway map folded in a coat pocket. Seoul's metro lines are identified by numbered circles in flat, committed colors, and the whole city navigates by them without thinking. A roundel does three jobs at once: the fill shows the color, the number gives it an address, and the circle makes it feel like infrastructure rather than decoration.

So the scheme adopted the format as its legend. The eight colors are numbered one through eight in the order they matter: text first, keywords second, down to comments in fog at the end of the line. On the landing page the roundels run across the title bar of the code specimen, joined by a thin connector, exactly the way stations sit on a route diagram. The swatch cards repeat the same numbers, so the strip works as a table of contents for the section below it.

The pleasant surprise was how well the strip survives shrinking. In a browser tab, in a social preview, in the tiny screenshot of a gallery card, eight colored dots on a line stay legible long after any text has dissolved. A legend that still reads at sixty pixels wide is the closest thing a color scheme gets to a logo.
