If they weren't so clueless they would have made the disfellowshipped person colorless. That is really the reality of it...the disfellowshipped walk among them as if they are ghosts, apparitions. Nobody looking at them, walking by them as if they are not even there. But no, they make her in color. And not just any color, but one of the most beautiful colors on earth, robins egg blue. Thats why I think whoever painted this must be sympathetic to ttatt.
Some of you mentioned Pleasantville, which probably most people haven't seen. it also reminds me of wizard of oz, where Dorothy leaves bleak, brown and gray Kansas and opens the door to the gorgeous color of OZ, a wonderland to explore.
How could they be so naive? That movie is from the 30's, they're not too old to have seen it :).
