The information i did find, indicates Ektachrome was very good with greens.
I called my dealer and talked with them (40 years of experience ) and they too felt Kodachrome was much warmer, with the Ekachrome being cooler.
Of course lighting conditons and which IOS used effects the temperature.
Long ago and i mean a reall long time, say the 50's I seem to recall an easy way to remember the temperature shifts was the color of theboxes. Remember how organge that Agfa box was? That of course could be too much fixer on the brain, or urban myth, but that does bring back memories.
Thanks for the info.
