Etymology

The term "blue-green" is a straightforward compound formed by combining the words "blue" and "green," both of which originate from Old English. "Blue" derives from Old English "blǣwen," influenced by Old Norse "blár," while "green" comes from Old English "grēne," related to the verb "growan" (to grow). The compound reflects a logical blending of colors, commonly used to describe hues in nature (e.g., water, foliage) or synthetic pigments.
