I would guess at violet or reddish but have no way of knowing.

Point being that it's the techies on this list that convinced me of the
relationship and the exact correlations are not of much concern to me
because, IMO if the CS has a color...it's drain filler. [That's just me and
others can use what they want to] There is still some question in my mind
as to what makes the particles grow larger and exactly what the crystaline
structure is composed of.
