Working at a 100 year old Candle Company, ColonialCandle.com, I asked the candle making team of experts. When we have done this experiment using taper candles, the white candle should burn the fastest as there are no colorants to impede the capillary action of the wax through the wick. That is making sure that all things are equal in the candle make up such as wick, and wax. Unless of course , the white candle has an optical bleach in it to have the illusion of being more white. The optical bleach is a pigment and would cause the rate of consumption to be less. Only thing to add is a darker candle can sometimes burn faster because a dark color holds more heat and can cause the candle to burn slightly faster. But your point of all things being equal is the most important factor.
