Although I'm reluctant to resort to screen caps, there is a relatively simple comparison for colour emphasis/de-emphasis in Desk Set...most of its set dressings were re-used in Irwin Allen's Voyage to the Bottom of the Sea only a couple of years later (also a Fox Adler-era production):

Even allowing for inconsistencies in the preservation and remastering of each picture, if there is some huge difference in the attention to grayscale here, I don't see it. Just looks like De Luxe colour from Fox circa '57 to '61.
NOTE: Caps courtesy of Blu-ray.com, chosen mainly for the consistency of their capture specs.
Thanks for this, and Happy New Year to you all. This comparison is quite illuminating. I couldn't believe that there could be so much blue/green in the sets, but now I see it was entirely intentional. I must admit that I was swayed somewhat by comparing the bluray of Desk Set with the DVD, and couldn't see where the blue was coming from!
