Yea Mister Groinpuller, there's no hope.
I forget which goth rocker said it but I always loved this quote...

"If there was a colour blacker than black, I would paint my room that colour and buy some black furniture to brighten the place up."

I guess Pinter was just trying to furnish and brighten up Beckett's black room.

But there is no colour Blacker than Black, Pinter Head! :|
