    The hottest part of a gas flame is at the point when the gas is actually burning (i.e., oxidizing).  And that's in the colorless (maybe slightly blue) part of the flame nearest the vent.  That orange/yellow part of the flame is actually where residual (unburned) carbon has been heated by the flame and caused to glow.  Same deal with wood burning.  The really hot part is near the wood where the wood is actually burning.  The yellow/orange section is again glowing carbon/ash.

    Not to cold - white, blue, orange.

    The brightest blue part is the hottest and that's usually the tip.  I'm thinking of a flame from a propane or natural gas burner.
