A question about Technicolor

Watching a "B+" movie w Gene Kelly and Rita Hayworth-- it came to me that the acuity of the image is pretty remarkable -- is it that the Technicolor process increased the contrast around the edges a la "unsharp masking"?

Forgive me, I made a lot of unsharp masks for BW negatives using 4x5 film.

What you possibly saw was 'image enhancement'. It's not the Technicolor process but the telecine to transfer film to video. However IMO enhancement products that are 'visible' are artifacts. Done correctly you shouldn't see the enhancement artifacts per se, just a good image.
