     Kodachrome was brilliant because it was intended for 
direct viewing and projection and because people of the time 
wanted brilliant color. Technicolor made the same decision 
about how it should look even though it was capable of very 
subtle color. Ektachrome had different dyes and a different 
gamut of color.  Certainly color advertisements made using 
it never looked as good as Kodachrome, not even Kodak's 
promotional stuff.
     Before Kodachrome there were a number of color 
processes but the one most used for commercial purposes was 
to make color separation negatives using a "one-shot" 
camera. This was a camera with a beam splitter and filters 
in it.  The negatives were then printed using a three-color 
process, usually three color carbon until about the late 
1930s when Kodak aquired the dye transfer process and made 
it easier to use.  Three color carbon or carbro is an 
extremely difficult process. There were a two or three labs 
in New York who catered to the advertising industry and did 
nothing else. In person these prints are quite beautiful but 
did not reproduce as well as Kodachrome transparencies for 
four-color half-tone printing.  Kodachrome did not totally 
supplant this process and both the cameras and printing 
materials continued to be available into the mid 1950s, 
partly because they did not need an outside processor, 
namely Kodak, to be used.
     Eventually, Ektachrome and Ektacolor (negative color 
film) were perfected sufficiently to supplant other 
processes, helped by Kodak's discontinuance of Kodachrome in 
commercial formats.
     BTW Kodak also made low-contrast Kodachrome for 
indirect use, that is for making duplicates or making 
reflection prints.
     Unfortunately, you have hit a special interest of mine 
and so all this OT stuff. Enough, enough.
