Backdrop options

[truephotoga]

I was wondering what are some of the common backdrops that other photogs keep in stock? I currently only have a roll of grey seamless and white muslin. I would like to purchase more seamless paper rolls, but not sure of what colors to get. Thanks!!

been meaning to get some gray muslin....

anyway, we use mostly black muslin.
sometimes white muslin.
we also have a chromakey (green screen) that sees some very occasional use.
