Sun,
white fire is one of the most basic pyrotechnic compositions. I suggest you either borrow or buy a good book on pyrotechnics. Note, however, that a list of ingredients is only the beginning to understand how to make a pyrotechnic effect, just like a list of ingredients for a recipe is only the first stage in creating a delicious dish.
If you want a good source of pyrotechnic books, go to:

There are many to chose from. As in any craft, the more you read and learn, the better and safer you will be. Undertaking the mixing of pyrotechnic compositions should not be attempted without serious thought for the consequences and you should always have an emergency and safety plan. Like any other chemical work, you will, of course, keep a detailed lab book on what materials you have and the procedures you follow. Consistency is something which the masters of fireworks are always striving for. As for safety, you have to ask the question: which parts of my body do I not mind losing? If you can answer this question and formulate a good safety plan, then you might be ready to start along the road to being a pyrotechnic chemist.
