The dynamic duo of Siskel and Ebert remarked on one of their shows
that the colourisation process destroyed the relative intensities of
the objects in the film, so that when you play a colourised film
on a B&W set the shades come out different. They objected to this on
the grounds that the really good directors took great care when making
B&W films to make sure that the shading took full advantage of the B&W
medium.
Are these assumptions true, or a bunch of B. S. (bean sprouts)?

(1) Does the colourisation process alter the original intensities?

(2) Did directors really care that much about the shading and contrasts,
so much so that the altering done by colourisation would destroy the
effect?

I am cross-posting this to net.sci in case anyone there knows or cares.

You bet. That's the responsibility of the art director and set decorator.
The cinematographer would also be concerned. So even if the director was
"visually blind" :-) there were enough people to keep him out of trouble.

I haven't really noticed colourization destroying the effect because,
quite frankly, its been little more than a tint job. It is impossible
to reconstruct the necessary information from a B&W print, so you get
the obvious colouration: green grass, blue sky (or more frequently
bald sky), pink skin tones. Everything else looks more like a sepia
tint.
