Javier,

Though I haven't done this in ImageJ, I would recommend converting your
images from RGB to HSV (Hue, Saturation, Value/lightness,
http://www.siggraph.org/education/materials/HyperGraph/color/colorhs.htm).
It will then be a fairly simple matter to filter pixels based on Hue value,
replacing undesired hue values with the chosen background value.  Then
convert back to RGB.

Think of it as being analogous to an FFT for color...

So my question:
Is there any way (or plugin) of post-processing such images to remove the
orange background while maintaining the green signal?
