Thank you, guys for all the responses.
I understand how fluorescence can be responsible for the color change.
(I mentioned that possibility in my original e-mail.)
My question was rather, - how can you deal with that... (if at all).

Bill, thank you for your story about the wedding problems.
So, did you find any solution to it back then?


========================================================
As for the original photo, its colors, and my various viewing sources,
I made some additional observations last night, which got me confused 
even further.

Here are my "viewing sources":
(1) I have a IPS LCD monitor from Dell (U2410, IIRC), that was 
(not quite-calibrated but) tuned using the calibration software tool
that came with it. It seemed to produce rather accurate colors so far.
This gets attached to my laptop.


(2) I also have a large old "professional" series CRT monitor attached to my 
home desktop. It has been tuned in a manner similar to the described
above.
It's been providing consistency 1) with the actual object colors, 
2) with the colors coming from the Epson R2880,
and 3) with the back display of my K-7.

(3) I also looked at the photos in question directly on my laptop's screen.

(4) Finally, I see how the photos look on the back display of the K-7.

Results:
Sources (2-4) as labeled above showed the same (bluish) color for the
original shot in question
http://42graphy.org/snapshots/misc/_IR31001.jpg .

Source (1) showed purple color close to the expected one.
Also, the greens were less yellow, and hence closer to the original
(as seen by a naked eye).
On the same monitor, the "purple" color image for which I sent the link
yesterday:
http://static.heels.com/img/high_heels_blog/wp-content/uploads/2008/04/purple1.jpg
became reddish.

The laptop's display (3) color was easily tuned to match those of (1)
by bumping up the "Hue" parameter (from 0 to ~30-33) in the Intel Graphics 
Properties.
(I actually remember doing the same thing previously for the projector
used to display photos from the same laptop, - for my photo slide show 
presentations last Fall.)

BUT then, I am confused which of my "viewing sources" are (close to) 
calibrated, and which are not.
If the source (1) and re-tuned (3) are the (more) correct settings, 
(because they match the original objects as seen by the naked eye)
then I am puzzled by
1) Why the camera's back LCD is not showing these colors, but
rather colors that I saw on (2)-(4).
2) If (2) is not calibrated properly, - why the color usually match
what I expect, and the printed colors (using calibrated paper profiles).
3) Why the "purple" poster from the link posted above looks almost red,
on (1).

I guess, I need some good reliable (i.e. known not to change colors
depending on the light) colored photo-target for proper screen
calibration. Or I should bite the..  err... buy Spyder 3 or another 
such calibration device.

Speaking of which, - I would appreciate your recommendations for the
screen calibration devices/tools and procedures.

Thank you,

Igor
