I thought it was very similar to Jango's silver color, with the only difference being the cape, helmet being red and minor differences in the armor details. I know the bhg has some pics of him, and I've found some good ones on some other forums, or even google images. There is a CRL on the bounty hunters guild if you want a better reference for the different pieces. It lists all of the details that the 501st consider necessary for an accurate costume.
