Usually a colored candle. I think yellow burns the fastest of all. It has to do with the chemicals associated with the pigment of the color.
I'm pretty sure white burns faster
yes because a white candle burns out faster
Example: white candle burns. white reflects light so heat is deflected also black candle burns. black absorbs light and heat therefore would burn faster than a white candle.
A white candle could burn faster because it could be made out of different material as the colored one to make the white color. To make the color of the colored candle it would take different material
The color is not important for the burning of a candle.

white candles
White or colored candles may burn at the same rate or at different rates. The rate at which a candle burns is dependent on the size and composition of the wick, and the thickness, composition, and melting / vaporization rate of the candle wax.
The coloring is usually just on the outside of a lipid candle, the whick burns in a modern candle, if its an old oil candle, it might have color that burns due to its chemicals.
Colored candles burn slower than white candles!
Probable it is the influence of impurities but the difference is minimal.
