Actually, now that I look at the list again, I think Blue Black would be closer to Black Plum Pearl than Pacific Blue Pearl... So, the list would be as follows.
1. Radiant Silver - This is Slick Silver in Korea
2. Harbor Gray Metallic - This is Hyper Metallic in Korea
3. Remington Red - This is Venetian Red in Korea
4. Black Plum Pearl - This is probably close to Blue Black in Korea
5. Phantom Black Metallic - Black Diamond in Korea
