I am not defending that definition of red, (nor am I defending Romansh's definition of llusion);

I think it depends on what the "illusion" actually concerns. I would certainly agree that a percept is not an illusion in terms of what colour is perceived, BUT it can be interms of the physical colour of the object being perceived. (I hope I don't have to go over the definition of "physical colour" again!)
