Christopher Doyle: In The Mood...

Another plea for recommendations here. After posting about the work of Rut Blees Luxemburg a few weeks ago, I've rewatched a bunch of bootleg Wong Kar Wai DVDs I picked up in Hong Kong last year. The director has worked with cinematographer Christopher Doyle on most of his features so far and between them they've established a very distinctive style, taking their cue from vintage noir and retro-futurism, with plenty of slo-mo camera work and unusual viewpoints.

It is the over-saturated colours and heavy contrasts that I'm particularly interested in, especially on 2046 and In The Mood For Love. I've seen it called "Vanguard colour grading" but can't find a good explanation of this on the 'net. I'm guessing it's an expensive post-production filter of some sort but I'm sure there must be an easy way of getting similar effects in Photoshop - a few things I've tried look far too processed or heavy. If anybody can advise on a neat way to replicate this or maybe point me to an online tutorial somewhere, that'd be much appreciated. Here is the kind of thing I mean...
