Fluorescent lights tend to give a greenish cast.

Any color shift produced by a lens (especially by a fine lens like
yours) perhaps be only measured/detected under strictly controlled
conditions.

I've been using Pentax 31/1.8 Ltd lens for the past few months, and I
noticed that it tends to produce lots of red. I mean that the red
channel frequently appears to be somewhat over-saturated.
In many of those cases I can fix that in LR by dialing down the saturation
of the red channel under HSL menu in the "Develop" module (LR 3.6)
to about -10 -- -20.
This is especially noticeable in extremely red lips and/or red faces
overall.
Does anybody else observe this trend?
I wonder if it might be
1. the specifics of my scenes (relatively low-light, mostly fluorescent
lights)
2. the specifics of my lens.
3. specifics of the LR 3.x process [that is taken care of in 5.x]
(I don't see this with other lenses)
4. something else...
