Something else to consider trying is changing the exposure setting. If your camcorder allows you to increase or decrease the exposure level, you might want to reduce it a bit. This is because fireworks (or other nightime shots) are bright pinpoints of light on a largely dark sky - and sometimes auto-exposure can over-compensate for this and make those points of light just TOO bright, thus burning them out and losing the colour. A perfect example of this is at WDW; when shooting the globe in the Illuminations nightime show at EPCOT, auto-exposure turns it all white and loses a lot of the detail.

Might be worth thinking about, anyway.
