I understand if you want to maintain some warmth, but more often than not what comes out in low light shooting looks like somone pissed all over the picture. Sometimes you mmight opt to use it, other times not.
It should give you a better idea of how it looks. here are a couple test shots i did here at my office.
The first one is with AUTO white balance. This is NOT how it looks to the eye
2nd one is after i did the coffee filter expodisc. This is much much more accurate with what is seen
