Big Kahuna is a light-medium, yellow gold with warm undertones and a fine, pearly shimmer. It had semi-opaque pigmentation that was buildable to opaque coverage with two layers (it was nearly opaque over primer, though). The consistency was soft, a touch dusty but not prone to sheering out, and blendable on the skin. It wore well for seven and a half hours on me.
