A yellow flame is yellow because of unburned carbon(soot) which is becoming incandescent in the heat of the flame. In very accurate gravimetric analysis, this soot can deposit on the bottom of your crucible/evaporating dish/beaker and add mass to it, which will throw off your results.
Plus, a blue flame is a lot hotter.

a blue flame is much higher of a temperature. and it is usually used for intensity on a particular area of what it is that you are burning.
