Actually, I believe there's one chord missing in that progression, which you can get by without.

Try:
(Em)I see a red door and I (B7)want it painted black
(Em)No colours anymore I (B7)want them to turn black
(Em)I (D)see the(G)girls walk (D)by dressed (A)in their summer (B7)clothes
(Em)I (D)have to (G)turn my (D)head, un-(A)til the darkness(B7)goes

In truth, I came across this thread because I'm looking for a possible correction for one of the verses.

The line "No more will my green sea go turn a deeper blue" just makes no damn sense at all. I figure it HAS to be a mondegreen; yet every source I've tried on the 'net has it that way. Anybody got any ideas or info?

PS: Maybe it's not strictly folk, but my band has the coolest possible gig coming up, and Paint It Black is the one request we have. The gig: we're performing at a Goth wedding ON Halloween!
