See page 34 of the manual regarding the color temperature.
LCD projectors always tend to lean towards the blues. The lowest preset is 6500K which is a little high. Read the first half of this Wiki http://en.wikipedia.org/wiki/Color_temperature
the second half contains WAY too much math! and i was told there would be no math.
If you're shooting with a standard flash you would be slightly warmer than the 6500K that the projector has as a preset. Most projectors seem to default to the highest temp. ~9300K. This gives the most punch to the whites and appears brighter but leaves all your images blue.
If you really want to balance this out you might want to make sure that the monitor you use to view/edit your pics is calibrated the same as your projector to eliminate the color shifting.
What I usually use to match multiple projectors is a grey step scale.
Just horizontal lines starting at 0% white and going to 100% white in 10% steps. (sometimes 5% steps for the first 20% to increase resolution in the extreme whites/blacks)
This is usually used for contrast and brightness adjustments but if you put it on your projector and play with the user settings for color temp. you'll see the results.
You can also get color temp. reference cards and use them to calibrate your camera for the display color of the projector..
Of course ambient light throws a wrench in this, especially in front projection, is it incandescent or flourescent?
Not such an easy question.. is it?
