I think Saving Private Ryan and Peal Harbour were shot in Technicolor.

They were shot on color negative film, just like any other production. Technicolor made dye transfer prints of Pearl Harbour (and possibly Saving Private Ryan, I'm not 100% sure), and this is probably what you're thinking of. It is not meaningful to talk of movies being "shot in Technicolor", unless you mean they were shot using the three-strip camera, but this has not been done since the 1950s.
