C41 in e6 in my limited experience produces flat and muddy slides. The one exception in tmax CN (chromogenic bw) when rated @ 12 or 25 and processed normal it produces a beautiful cyan cast slide. Don't let my recommendation or lack thereof keep you from experimenting on your own.
EPP, EPN EPR -- all older daylight chromes from Kodak have blue/yellow cross over when shot in daylight (blue shadows, yellow mids and highlights). the newer Kodak and most Fuji films have a green cast which if under exposed for the subject will get magenta/green crossover as you'll run out of density as you try and kill the green, but mostly these films suffer from green and green yellow casts.
All of these films tend to react strongly when shot under manmade lights. Which is to say that the light temp tends get exaggerated in the neg.
One problem with scanning xprocessed chromes is the dmax of the film a xprocessed neg will generally exceed the capabilities of most scanners in the highlights.
I hope that helps.
