Magenta cast in C41?

[RPC]

That means if the Kodak pdf speak to example about increased red color, it means that on the print that it will be blueish? That it means the opposite color?

See post #20 about colors and their opposites.

My Intention is to get my own negatives, with my own saturation and color density.

I have no idea what you mean by "my own saturation and color density." If you mean a saturation and density different from what would be obtained by normal C-41 processing then your chance of getting anything useful is rather slim. Color processing is much more complicated and demanding than B&W processing. Unless you have an understanding of chemistry I would not recommend mixing your own color chemistry.
