I haven't seen THE VISIT, but the shade of yellow in ljay's image - just a hint of greenishness - can also suggest illness, jaundice and death.
Sounds ripe for Kander & Ebb to have expounded upon!
This show is probably the one I'm most interested in, out of curiosity. Because nothing about THE VISIT as a play is in anyway comforting or reassuring.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
