You might be able to run your VIN to find out the model code. Basically the four listed for 2013 are two C version for California emission models, and two 49 state ones; XTX12DG and XTZ12DW.
The 2013 Super Ten colors were Matte Gray & Pearl White so I'm fairly certain that the XTZ12DG is gray and the XTZ12DW is white. The link I gave above is to the XTZ12DW page, so I'm not sure why they show two fender p/n's. You could likely verify with your dealer too, asking about the P3 or P4.
