Here is the follow-Up, I had inquired to Wittner-Cinetec in Germany, They Have assured me that their Aviphot Chrome 200 color slide film is not yellow, here is the email they sent to me:
Dear Mr. Icanberry,
thank you for your message.
Here you will find some sample pictures of our batch
The are NOT color corrected!
Emulsion No. is 6782.16, currently the same for Super 8 and 35mm still film (same wide roll).
I do not know what could cause this yellow colour cast, which you have experienced.
But our batch does not show this problem obviously.
If you need any further assistance, please feel free to contact me again.
Mit freundlichen Grüßen
