Plural of coloring: substances used to add color to something, or the act and result of adding color to objects.
From Middle English 'coloren' + Old French 'colorer,' from Latin 'colorare' (to make colored). The suffix '-ing' indicates both the action and the result, while the plural '-s' shows multiple instances or types.
Food colorings have a wild history—before synthetic dyes, people extracted colors from bugs (cochineal red), plants (indigo blue), and minerals, and some of those ancient sources are still considered safer than modern alternatives.
