/**
 * ECMA-376 §18.8.27 — the legacy indexed colour palette a `<color indexed="N">`
 * refers to. It predates `rgb` and theme colours and is still what Excel writes
 * for anything picked from the classic 40-colour dropdown, so a file using it
 * is not unusual: tdf58243.xlsx colours its header cells `indexed="10"`, and
 * ignoring the attribute rendered them black where every other reader shows red.
 *
 * Entries 0-7 are repeated at 8-15 (a quirk of the original palette); 64 and 65
 * are the system foreground and background.
