Chartreuse is a color between yellow and what?

Green is correct because chartreuse sits between yellow and green on the color wheel—essentially a vivid yellow‑green. In color models, its hue is around 90°, midway between pure yellow (60°) and pure green (120°). The name comes from Chartreuse, a French liqueur made by Carthusian monks, which famously appears in both green and yellow varieties—an easy source of confusion. To remember it, think of lime peel, neon tennis balls, or high‑visibility safety gear: all live in that yellow‑green zone. Designers often use chartreuse to convey energy and attract attention because the human eye is especially sensitive to these wavelengths.
