The characteristic color of this alloy, a popular choice for jewelry and decorative objects, arises from the presence of copper in its composition. The increased proportion of copper deepens the reddish hue, resulting in a warmer, more pronounced tint. For example, a high copper content will manifest as a distinctly reddish appearance when compared to alloys with lower proportions.
This coloration enhances aesthetic appeal and provides a perceived sense of warmth and luxury. Historically, its distinct appearance allowed for differentiation from traditional yellow gold, offering designers and consumers a broader spectrum of stylistic options. The metal’s visual properties contribute to its desirability and perceived value.
