Cobalt can have is of pink colour, also fuchsia purple/pink, some violet depending of the angle, and also a nice red as you can see on the picture.
In an old german alchemical book, (sorry I don't remember the title), Cobalt was associated to planet Mars.
If you have any experience about this metal, let me know :)
Of course, this pink colour could be realted to a more feminine energy like Jupiter or Venus. A deeper exploration of this metal will surely learn us more.
