The bulk update request #993 is pending approval.

change category black_and_brown (43) -> meta
create implication black_and_brown (43) -> monochrome (398255)

Reason: Pretty obvious...

There might be more monochrome stuff that needs to be implicated there and moved to the Meta category. Feel free to add.

wouldn't some of those images in black and brown just be considered Sepia?

edit: oh, sepia implicates monochrome.

+1 for this implication and category change. This will match the implications of similar tags, since it looks like a bunch of [color]_and_[color] tags currently implicate monochrome.
