If you want to go to the expence of a 5th color, you should be able
ot get close  with a pantone ink. But I doubt your client will
appreciate the extra expense.

Other than that you are stuck using some combination of Cyan,
Magenta, and black for your color. Truematch and Pantone both make
printed swatch books of CMYK colors that will allow you to estimate
the best combination for your need.

the blues allways print more purple to the eye than what you see on
screen in my experience.
