Notes

Medium Aquamarine is the muted mid-saturation cousin of Aquamarine, sitting in the soft-mint zone of the colour wheel. The CSS hex reads as calm and slightly nostalgic, with low enough chroma to work as a primary surface for wellness, beauty, and editorial brands. Paired with cream it softens further; with deep teal it gains tonal depth. Against white it provides reasonable separation as a panel background but is too pale for body text - contrast fails AA at every size, so it lives as a surface tone with dark text overlays.
