Copper #2 has a transparent base with flecks of white gold and warmer, pale gold sparkle. It worked more as a sparkling top coat or a wash of shimmer/sparkle rather than a standalone eyeshadow, which may be just fine for some and a deal-breaker for others; I wish Dior had more insight into coverage-level for these types of shades. The texture was more powdery than ideal, which resulted in some fallout during application. It lasted decently for seven and a half hours but had some fallout over time. I would definitely use this one with a setting spray or the like to give it better hold.
