Well, without a sense that can detect color, it would just be an arbitrary undetectable property something might have, right? So it would be ... dependent on what other objects B9 is aware of, I think. The precise hypothesis of "all [objects that we know are blue] share a common property I cannot perceive with this camera" should be highly conjunctive, and therefore low, unless B9 has observed humans reacting to them because of their coloration. And even then, "blue" would be defined only in terms of what other objects have it, not a specific input type from the camera.

I suspect I'm missing the point of this question, somehow.
