Color correction for Rollei Digibase CR200?

[StorminMatt]

Because I have heard that it does a decent job of duplicating the look of Kodachrome, I recently tried shooting a roll of Rollei Digibase CR200. However, what I got didn't look too much like Kodachrome. What I got was 36 slides with a rather strong yellowish cast. Looking around, I see that this is what ALOT of other people get from this film. So I'm just wondering, what kind of filter are people typically using to correct this yellowish cast and give me more neutral, Kodachrome colors? I figure that maybe some sort of cooling filter might work. But what have you had good luck with?
