I'm not in front of my system, but I would suggest making multiple overlaid tracks. Use the Hue saturation effect on the lower track with saturation all the way down to give you a black & white image. Then on the upper track, you essentially want an inverted chroma key (with alpha channel so the lower track shows through.) Taking a guess, you might try using Chroma key (HSV) and select the color directly 180 degrees opposite to red on the wheel, then increase the threshold to near maximum as you prefer. If that doesn't work, you can try essentially creating a mask using Chroma key to show everything but the red you want on a third track, then using the Difference Key effect on this and the original track. Hope that helps!
