Hi Bobtail,
You didn't say what kind of camera you are using. If it is a digital SLR you should have a "White Balance" option either via a knob, button or buried somewhere deep in the menu structure. You would select either "Auto" or "Fluorescent". Some non-SLRs have this option in their menus as well. If you are using a film camera and then scanning the negatives the only way to avoid this would be via filters or by using a non-daylight film. I haven't used film in such a long time I've forgotten what filter or film types to use but it would be easy to dig up the info.
There is normally no loss of fidelity when using photoshop to correct the color balance if that's what you're worried about as your camera uses similar algorithms to achieve color balance. It's an annoyance though.
Since all color balance is based on the cameras idea of "what is white?" there will be a color shift regardless of what light source is used, so it won't matter what bulb type you've got. The default is normally "white as viewed under a midday sun" so taking pictures outdoors in sunlight yields optimal results while pictures taken indoors or in shade may have a yellow or blue cast respectively if there is no correction applied.
Edit: Andy, I just checked the Casio website. If you still have your users manual check page 116 "Advanced Settings" You can play with the various WB settings until you get the look you want for that particular shot. It has a couple of different Fluorescent settings so just play around. The tungsten setting is for indoor shots so that will eliminate the yellow cast. if you've lost the manual you can download it here:

Lord only knows why WB is considered an "advanced" setting when it affects every single shot on a camera...
Cheers,
