I personally like the default rendering that Aperture has. It's much more faithful in my experience than the Lightroom default rendering, which for my Canon was awful in the red/orange/yellow spectrum. The new profiles with LR 2.0 may have addressed this, but I moved away to Aperture in the interim as the LR 1.4.x renderings were so bad for me in a number of shots.
Anyway, is your monitor calibrated? You could always dial in some tint change toward the pink if that's it; but if your monitor is calibrated and your white balance is set properly (or you're balancing in Aperture) the renderings should be pretty faithful.
