|Left: Orange-Pacific, Right: Riveting|
Orange-Pacific is on my index and ring fingers, Riveting is on my middle and pinky nails. OP is more red toned and Riveting has much more gold. Also, OP took three coats to make opaque and Riveting only took two, plus R has a much better formula. If I'm not mistaken, I think OP is the older formula (it came out in the Surf Collection of 2007) which isn't Big-3 Free, that could account for the formula difference.
Hope this helped anyone out there wondering how these stacked up against one another! Oh, and on another "orange" note, I just got a new kitty! He's a long-haired domestic with orange and white fur. I named him Sawyer :D
