I believe the pearl paint colors were only available with the Touring trim. Love this car!
All Clarity PHEV sold in the US share a common palette: Platinum White Pearl, Solar Silver Metallic, Modern Steel Metallic, Crystal Black Pearl, Moonlit Forest Pearl (green) and Crimson Pearl. White, green and crimson have beige interiors, the other colors have black interiors.
The Clarity HFC comes in Bordeaux Red Metallic, Platinum White Pearl and Crystal Black Pearl. The red has a platinum gray leather interior, the other two have black leather.
The Clarity EV comes in Platinum White Pearl, Modern Steel Metallic and Vortex Blue Pearl. The white comes with black or gray leather, the other two with gray leather.
The distinction between Touring and Base in the PHEV is that the Base has soft-touch material on the dash and doors while the Touring has suede, the Base has cloth & pleather seats while the Touring has leather, the Base has manual seats while the Touring has power seats and 2 seat memory, and the Touring has navigation. All other aspects of both trims are identical. I know the Canadian spec is slightly different but I don't know about the Japanese spec, other than that the Japanese PHEV has ChaDeMo fast-charge capability.
