I currently use Color Schemer Studio to assist me in creating color palettes. I have a specific green that I am using (#B9DE56) and would like to know what a complementary reddish color would be to use in conjunction with this green.
What is the best way to go about doing this?
b44690 is the complement. You look for the exact complement directly opposite on the color wheel. I don't know anything about the program you're using.
You could use Adobe Illustrators in-built Color Guide, you find that as a tab by the color palette. It helps you select schemes from the color circle. Be they analogous (neighbours in the color cicle) or complementary (opposite in the color circle).
When you find a nice color scheme you could use Illustrators Recolor Artwork (found at the top bar when one or multiple objects are selected) or import it to Photoshop and recolor it with a Hue-adjustment to modify it.

In CS4-package this kuler panel is accessible from within photoshop.
I've just read a Leo Sandbergs book Imagine: Creating Art for Entertainment, he talks ALOT about color. It's always good to Understand how colors work and why one is "better" than the other.

it suggests that the complementary red for your green is #DE5692
