This color seems surprisingly deep and blue for a malachite. We are not very sure about this color swatch, but it comes from a scholarly article where the version is not specified. The color appeared similar to Zecchi’s picture of their Deep version, so we’ll go with that, even though this is a surprisingly vibrant deep green for a malachite. From a second source we wwere again surprised by the depth of this color when we saw a nearly empty bottle of Zecchi Malachite Green Deep. A third source, a picture from the Zecchi shop, shows this hue as hex color (#348070). Zecchi also makes a Malachite Green Light.
