I agree with what you’re saying about the “colorized look” These were my exact thoughts when I first viewed the despecialized version. Not as distacting as bad CGI everywhere but I wish the color was a little more natural looking. maybe in V3.0?
It’s the “Technicolor film look”. Not colorized, so much as Wizard of Oz. In 3.0, Harmy’s mentioned he’ll do multiple color grades: a better-corrected Technicolor film grade, a grade to match the look of non-Technicolor film prints, and I think maybe a third one that just aims for the balanced neutral look rather than one of the theatrical film looks.
