Just for the record here - the lighter the color, the less true colloidal silver. Clear is inferior. Even yellow, gold and light amber are inferior to the true colloidal silver of nanometer and sub-nanometer size particles, whose color is dark amber or brown.
A lot of silver manufacturers and silver maker manufacturers would have you believe different because so few of them are able to make a product that is very high in nanometer sized particles of true colloidal silver, but they are deceptively wrong when they allege that.
