Color of Colloid

My Colloids color is faint yellow on the first batch and the second batch is more yellow. It seems to be as good or better than the $30 per 4 ounce silver I used to buy.

I wonder why it isn't clearer though. I make my own distilled water. Maybe it's the charcoal filter on the output?. Maybe I should clean the kettle better? Maybe I should by some better water at the store? Maybe that's just the way it's going to be and nobody can do anything about it, nor should they because its as good as it can be?
