One thing that I've found fascinating is how suspended particles can change the color of solutions in unexpected ways. Recently I've observed how an insoluble white impurity in some copper(II) acetate solution made the solution look much more blue- more like copper sulfate color rather than the teal that the acetate is. Also, suspended manganese dioxide in potassium permanganate can make the solution appear blood red (which was actually what the mystery I brought up in another thread was)

That's crazy! Especially suspended metal 'micro-particles'. Can totally give you a wrong idea about coloration.
