I had to turn the pc on to answer a bit more extensively.

Considering that films always get a color timing "treatment", obviously what we find on the film print won't necessarily (probably never) match real life colours.

Also, you can't certainly judge from shots of models because those are the most heavily alterated in terms of colours, the interior stuff not as much.

Even with all the important limitations of such analysis in mind, I can still say that:

yes, the colour of those rare RAF jackets could be elusive for who hasn't owned one (like most of the people on the RPF who were judging on any picture from any source they found). Having had one I can still see what is reasonably correct or not. My observation is also based on other details such as the golden wing patch (which is an unlikely yellow in the LD as opposed to the real gold it's supposed to be and this is better represented in DVD and BD), the shoulder patch and the buttons (which are black in the original jacket, not exactly the colour shown in the LD).

The LD version, from a good few details I can spot, is the least faithful to "real life" look. I still think BD is too "bright" looking and it's not "right", probably they killed some colours in the making... but I would still say that between the DVD and the BD there is some better representation of what "could have been" to begin with. The '99 DVD in particular seems to be the most spot on, take it for what is worth.

Again, that's just an extra consideration for this thread. Obviously whatever you find in the film stock is LAW, but then again, also those have black fading out in time. I've seen an original copy of Empire Strikes back with all the black that had turned into brown (the film itself was crisp clear)
