I am no guru, but I do know about yellow CS (because I have made it more than once).
I am somewhat of a perfectionist, so yellow CS annoys me.
I know it means some impurity was present during the brewing process.
Contrary to Neville, I don't drink it. It means clumping and larger particle sizes, and I want the most highly ionic content possible. In my case, yellow CS is most likely caused by touching something, most likely the electrodes, during cleaning. I tend to be clumsy.
It could also be something on the jar or in the water.
I usually stop it by carefully cleaning the electrodes with 3% h202 (drugstore stuff). Careful not to touch.
I then rinse the bottle a couple of times with distilled water.
Careful not to touch while doing this.
The next few batches should be ok.
If not, I get rid of that jar and try a different or new one.
If that does not work, I try new electrodes.
Usually, careful cleaning with h202 and rinsing of the bottle with distilled water takes care of the problem.

Meantime, I'll offer you an individuals assessment on your colour thing...don't worry about it, if you're making good quality stuff {meaning no mud or gravel laying in the bottom of your storage vessels} colour is not an issue. And the HP thing...shouldn't need it, and again, if you're making good quality stuff why would you want to hit it with HP? Don't be phased by colour, unless it's a murky colour.

There ya go Dee, I've filled in a gap til one of your guru's comes walzing thru the door <g>.
