It's worth noting that, as far as I have read, everyone with access to proper prints of the original theatrical version of "Star Wars" agree that the colours were all over the place to begin with. Harmy's reconstruction is going to look wildly inconsistent, because that's just the way it was. In that respect, even the pre-DC LDs seem to have had a certain amount of correction applied to them.

So if you're looking for 100% grey Death Star walls or realistic colours, this may not be the project for you to begin with. I'm personally looking forward to seeing this version, cause... well... I never have!
