This is why I always either make a print copy, if possible, or never give the go ahead until having received the galley PDF for approval from the printer, which generally displays at 100% and that's "actual business card size" so you have a much better sense of what the end result will be.
I designed my cards using MS-Publisher, and printed I don't know how many trials. But even then, there are issues with what a given ink color looks like when it "hits the page" versus on the screen. I had a great home print, and galley copy, but the blue I used for address/phone/email did not "read" anything like it did on screen or on home print in the final result.
If you have to make a guess, go darker than you think you might need on a light background, and lighter than you think you might need to on a dark background.
I like the blue and green as well. The pink, as shown on-screen, is barely legible and although I love red I also know that subliminal messages that are attached to that color that I think one would rather avoid in our business.
