The appearance really doesn't change much at all; the pieces that my particular copy has in the newer colors are all interior or structure related parts, with the exception of the two lightsaber hilts on the tips of the front guns. There is a noticeable difference, more so in the two shades of dark gray than the lighter gray, but since so few of the parts are in the newer colors the overall effect is really minimal. I don't know how it would look if more of the larger plates had color issues, though.

Thanks to all for the help. I've looked into this a bit more at noticed a few things. The largest offender that I noticed in Dark Bluish Gray in my 4483 was Technic, Brick 6X8 with Open Center. Looking at Bricklink, the part was first released in 2001, so it was conceivably new enough that LEGO might not have had a large store of them by the time the color change happened (as per Sid Sidious's post). Further, looking at the sets the part was in, the brick was only ever produced in 4483 in Dark Gray, and only in 7260 Wookie Catamaran and 8769 Visorak's Gate in Dark Bluish Gray. I do have both the sets in which it was produced in Dark Bluish Gray, but unless the ones in my 4483 were originally that same color I simply wouldn't have enough to have both 4483 and 7260 built (which I currently do). In short, my question has been answered and it looks like the Dark Bluish Gray pieces are original to the kit. Thanks again for the help.

4483 is the only AT-AT I have, and the reason I ask is because the assortment seems oddly intentional, in the sense that for any given part ALL of that piece are always old or new, not just some. Perhaps it was some other mixup on my part, but I thought this might be the cause so I came here to see if anyone knew anything about this.

Thanks!

I've just spent some time rebuilding my old 4483 AT-AT (the later 2004 version in the blue box), and I'm noticing that some of the parts are consistently in the new Blue-Gray, while the majority are still in the older Dark Gray shades. Is this just an oversight on my part (mixing up the parts over time) or were there sets that actually ended up with mixed parts when LEGO started the color transition? EDIT: Sorry about the title, I'm quite new to all this. Could a mod perhaps shorten it to something like "Sets with mixed old and new colors?"? Thanks in advance for the help.

Hello all, Chris here, from PA, USA. Started building/collecting LEGO with the 2005 Star Wars Revenge of the Sith sets, and from there I became interested in older Star Wars sets, and further branched into old Castle, Pirates, and Space sets. I've been lurking around as a guest for quite some time, but I've finally decided to sign up as a member just recently, after a renewed burst of interest in LEGO. Glad to finally be a member, and looking forward to starting off here at Eurobricks.
