Here''s a link that I found. Link The article indicates that the alloy is brittle, and pictures a cast purple gold ''gem'' that looks a bit like an amethyst.

QVC in the US have been selling purple, brown, black, red, etc gold chains for a while. However I think these are a coating applied to a normal gold chain.
Recently, there was quite a discussion about brown gold on Orchid (a jeweller''s discussion list). As far as I remember, there seemed to be someone selling a brown gold alloy, but with a lot of working restrictions. There was also an alloy "recipe" posted a while back, but it didn''t seem to come out brown when tested.
Coated gold is much more common than these rather alchemical alloys.
