Any paint guys out there?

I need to know if Toyotas' paint color Thunder Cloud is the same thing as Thunder Grey? I just shot some sliders , and the 4runner is thunder cloud but the paint (as listed in PPG & DuPonts color books) only list Thunder grey so thats what I got! Anyhow it sure looks to be more of a purple hue grey silver metallic whereas mine does not seem to have quite the purple hue to it!?!?
I will be posting a thread here soon about the sliders , and the new rig we are building in this forum soon so hopefully the paint does indeed match.
Thanks,
Richard
