#2598: Graphic Designers explain

[Cueball stands in a lightly adorned room of a house, facing an open doorway. Each surface is painted an almost imperceptibly different shade of off-white, except the floor which is white. There is a rug, a couch with a pillow (white) and a book. There are two windows, in the right there is a potted plant. Knit Cap stands in the open doorway, as if about to enter the house, one foot at the threshold, but not on the floor inside. Cueball is reaching towards the doorway, inviting Knit Cap to enter.]

Cueball: Come on in! We just repainted.

Knit Cap: I… can’t.

If you want to set up a vampire-style barrier to keep graphic designers from entering your house, just paint every surface a slightly different shade of off-white.
