Thanks dskeith, that code worked perfectly. Thanks for that!

Took a second look. It seems that you're trying to iterate on a list that doesn't exist. xrange(0,0) returns None not []. This likely happens because the instanced effector can't access the MoData of the other cloner that's been instanced (or something like that). I've taken the liberty of reworking your code to be a bit more error-tolerant:

import c4d
from c4d.modules import mograph as mo

def main():
    # Retrieve User Inputs
    EB = op[c4d.ID_USERDATA,2]
    linked = op[c4d.ID_USERDATA,1]
    if linked is None:
        return True
    
    md = mo.GeGetMoData(op)
    if md is None:
        return True
    
    linked_md = mo.GeGetMoData(linked)
    if linked_md is None:
        return True
    
    md_count = md.GetCount()
    if not md_count:
        return True
    
    linked_md_count = linked_md.GetCount()
    if not linked_md_count:
        return True
    
    # If counts don't match between cloners, use the smaller number.
    clone_count = min([md_count, linked_md_count])
    
    colors = md.GetArray(c4d.MODATA_COLOR)
    if colors is None:
        return
    
    linked_colors = linked_md.GetArray(c4d.MODATA_COLOR)
    if linked_colors is None:
        return

    for i in xrange(clone_count):
        colors[i] = linked_colors[i] + (linked_colors[i] * c4d.Vector(EB))
    
    md.SetArray(c4d.MODATA_COLOR, colors, True)
    return True
    

if __name__=='__main__':
    main()

But looking at your scene I'm not sure you'll get the result you want trying to colorize one cloner with a cloner object it's cloning.
