What would affect the color of colloidal silver?

When it comes to colloidal solutions, the main parameters contributing to color change(plasmon) likely come down to particle type, size and density. Of which I'd add, the type parameter depends on whether one chooses to qualify ions as particles or not.

That said, out of all of the references, I'd consider the first paragraph to be the most complete under general guidelines. Whereas the other statements appear to support this by way of deductive chemistry. However, I'd also add that it may not always be feasible to apply observations from one generator to another given the inherent difference in process methods that exist between them. Which will undoubtedly affect the ionic to particulate balance for example. - NB. ions possess no tyndall or light scattering properties, in contrast to silver compounds etc.

Hope this helps.

PS. every parameter(voltage, temp, water, etc) will have an impacts on solution composition. ionic/particulate ratio, compound types, size, saturation limit and-so on and so-forth.
