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.
While the compounds released differ from candle to candle they all produce water vapor and carbon dioxide.
They are both Consumed in the process called Combustion.

Candle burning is the process called oxidation. This is, it's the reaction that takes place when a gaseous material reacts with oxygen, the wax needs to change to gaseous state for the reaction to take place.

You can use either term. 'Burned' and 'burnt' are variations on the same word, just like 'learned' and 'learnt'.So you could say, 'The candle had burned out', or 'The candle had burnt out'.
A possible description would be "burnt orange".
Try combinations of Yellow Ochre, Burnt Sienna and a touch of black. If too yellow, add more Burnt Sienna. Be careful with the amount of black so that it does not turn green. Experiment with these three and I think you can get it. Mae Daze

he put the candle in a tube until it burnt out, then placed a mint sprig in the tube. 27 days later he lit the candle again using sunlight and it burnt perfectly leading him to believe that the mint replaced whatever was lost when the candle was burning.
