Which mineral is commonly used as a color component for malachite?

Malachite is primarily composed of copper carbonate hydroxide, which is why copper is the key mineral that contributes to its vibrant green coloration. This distinctive green hue is due to the presence of copper ions within its crystal structure. When light interacts with these copper ions, it results in the characteristic rich green color that malachite is known for.

While other minerals may be present in malachite, the defining aspect of its color is due predominantly to copper. Iron and magnesium, although they may occur in various minerals, do not play a significant role in imparting color to malachite. Accent minerals could refer to various trace elements or inclusions that might appear in malachite, but they do not define its primary color. Thus, copper is the specific mineral that directly correlates with the color component of malachite.
