IMO I now think the best color-wise for both are the original DVDs because they struck a video master from the restored prints. Of course you then have to factor in the fluctuations caused by a 2000 era process but still at least for RW, the old DVD just has that spark that is lacking in even the new BD.
Vertigo plays far better in HD due to the massaging done, but both need a new and proper job done. Neither compares to their respective restorations. I have only seen the 35mm reduction of the 96 restoration, and none of the video editions come close to replicating the fine detail or grain structure let a lone color. RW was printed during the short lived IB revival and was just mind blowingly vivid.
Since I got the cheap UK set, I still need a US VERTIGO for the mono. Uni loves making us buy films dozens of times.
And nobody cares about poor TMWKTM, which was downright mutilated on the 2005 master which was then poorly redone for BD, leaving the 2001 DVD sourced from the LD analog era as the only respectable video copy.
And don't even get me started on the others....Family Plot is arguably the worst BD ever issued by a major studio.
