As promides. Surely I prefer the b/w version but maybe some
will also like this one. Lately I met a - lets just say - a young person
telling me she never watches b/w movies because, well, because
they are not in color.
Well, at least the picture shows my bad taste in choosing colors.
In my defense I have to say the b/w version was always in my mind
so the luminance was much more important than the hue. And e.g.
a white dress would have looked like a wedding dress so it had to
be something else but still quite bright.
The colors (and image maps) are all defined as "real world colors"
and the gray conversion is done by a macro. For the curious, below
is a code snipped how it is done.

Technicolors(tm) is standardized through the CieLab ?
I know that from the german RAL-colorsystem
( http://www.ral-digital.de/index_e.htm )
and the swedish NCS-colorsystem
(http://83.168.206.163/webbizz/mainPage/default.asp )
- but Technicolors(tm) ?

Every color can be expressed as L*a*b value, not only RAL,
NCS, PANTONE or whatever.
And it is "Technicolor" and this is one of the earliest
techniques to create color movies. And the term was not
meant really serious by me, just as a reference to the
time of the early 30ies.

Make me think of those post coloured movies. The colours are slightly overdone,
but it comes with the style. Very good overall, but I prefer the B/W version.

Although you did a great job on the color, I also prefer the B&W version. It
just suits the subject matter better. As for the folks who won't watch B&W
movies, I wouldn't concern myself with them too much. They're mostly the same
people who won't go to Shakespeare plays because they "talk English funny".

Silent golden movies, talkies,
Technicolor, long ago.
my younger ways stand clear,
clearer than my footprints
Stardom greats I've followed closely,
closer than the nearest heartbeat,
longer than expected, they were great!
Oh, I love, I love just to see them
acting on the silver screen, oh my,
Clark Gable, Fairbanks, Maureen O'Sullivan,
fantasy will fill my life
and I love fantasy so much!

Hey, awesome work on this render and lightsys in general.

You could add some old film grain to the final image. I wonder if this
wouldn't make your image looking even more real, what do you think?
Besides that, I like your idea. I will follow up.
