The movie was shot 60 years ago in Technicolor and the colors were still p e r f e c t. Reds and blues well saturated (King Lionhart and Robin Hoods costumes), the greens (Sherwood forest) excellent and even the difficult skintones were very good. Many films made 30 - 40 years later, including many series made for television (Rick Hunter, Cousteau's movies, etc.), lost an important part of their color content: desaturated colors, color casts, poor contrast, stained highlights, transparent shadows, etc. The difference between Technicolor and later color systems is that with Technicolor the dyes are introduced in the film when development is finished while in the other processes color is formed during (color)development via a reaction between development fall-out products and coupling agents present in each of the layers of the film. The Technicolor people have many colorants to choose from (often very stable); color-coupler film manufacturers can use only a limited selection of coupling products (often not stable at all). Technicolor has good archival qualities, more recent materials have not. Kodachrome works like Technicolor, E6 films use color couplers, like recent movie materials. Although the best E6 materials (Ektachrome, Velvia) have now color saturation and grain that is somewhat better than Kodachrome, sharpness and color permanence of Kodachrome is such that, in my opinion, it is still the best film for slides, if you don't project too often. I hope that Kodak will continue to manufacture and develop Kodachrome for a long time (at least until new digital media can record 20 million pixels on 24X36mm at reasonable cost). I want my slides to be permanent like Technicolor, not like more recent color print material. An added benefit is that the combination of Leica lens- and Kodachrome image quality somehow is magic.
