probably has to do with size of colloids- they scatter light in different colors with different sizes. You may not have reached max saturation, but maybe the current was higher, or maybe the ions were bumping into each other more and became a colloid. If it bothers you, you can wait a couple of days then add a drop or 2 of hydrogen peroxide, that often clears it up.

Hello,
I have a kind of technical question. If you brew a batch of CS for 8 hours and it comes out clear. Then you brew a new batch for 10 hours and it has a yellow tint. Does the yellow tint indicate that you have exceeded maximum saturation? Thank you in advance. John.
