As Raven said, it is not the name of the color but how it effects you by visual, through psychological/symbolic means. White can be subsituted for any color.
However, if you are like me and really want the color you can change it with crayons. This works best with white as a base. Find some crayons in the color you wish to use. Melt them down in a pot (cleans off glass better) and roll, dip or pour over your candle. When doing this, make sure you do not set your candle in the pot for an extended period as it will melt. You can also buy wax paints at some craft stores.
You can also carve/paint symbols or pictures onto your candle. Make sure that they represent what you are trying to accomplish. The symbol does not have to represent this to everyone else, just you.
