Advice on negating effects of Halogen quartz lights

With some trepidation I am asking this question of so many experienced photographers.
I am involved with a youth group and we have to supply photos for press/media publication on a frequent basis, also for use in our applications for grants.
We have recenty has new lighting fitted in our sports hall which is Halogen quarts and throws off a yellow hue. The problem is that with digital photography this hue is accentuated and renders some of the pictures unsuitable for press publication owing to the colors used in press printing.
I am searching for advice as to how to best overcome this problem and have been thinking along the lines of an umbrella of similar device to try and compensate for the halogen effect.
We are using for the photos both a Canon Powershot A590IS and a Casio Excillim camera and the Canon gives the better shots by far.
A sample image taken with the Canon can be seen here and any advice or suggestions would be appreciated. To give an idea as to the effect the lights have the walls of the hall are in fact painted off-white.

You can use a bluish color correction gel in front of the halogen (careful, halogen is hot, so don't put the gell on the light, but in front!) to bring up color temperature. In the photo you can see the ugly green fluorescent, so in addition to the bluish gel you could use a greenish gel to make the light equivalent to fluorescent, so that you end up with a single correction (in camera or post process) to render the final photo more naturally. I am not near my gel sample kit, but there might be a single Rosco gel that both warms and makes the light lightly greenish

Are the children lit by flash? If so, just put a gel roughly the color of those lights in front of the flash, and then adjust white balance so everything looks nice.
