What about *pale* brown?

Tim, thanks for your informative posts!
What about pale brown feces?

Here's why I ask: Because I find that when I'm on the computer extensively, it triggers smooth, voluminous, bowel movements - in a pale brown color.

I wonder if this is caused by EMFs - electromagnetic fields emitted by the monitor, which may cause me an acidic system, and thus the aforesaid bowel movements.

But at the same time, the EMF's may have been responsible for my recent urinary tract infection (with white blood cells "too numerous to count") - since EMF's are supposed to replicate micro-organisms.

So, here's how my situation ties in with what you stated, about yellow or green feces:

Would paler *brown* tawny feces (vs. medium-dark brown feces) be a red flag that someone either has bacterial infection, or else candida? Or should the red flag only be with an obvious yellow or green color?
