Most gas stoves burn very low mass hydrocarbons for fuel. These burn with a blue flame.

There are two completely different things going on when water (even boiling water) touches the flame. One is the cooling effect (caused by the heat extracted from the flame by the heat of vaporization required to turn the water into a gas).

The other is the introduction of very small amounts of Sodium which is dissolved in the water. Some of the electrons of the Sodium atoms become excited by the heat of the flame and jump to higher energy states. When they return to the ground state some release a photon of yellow light. This is identical to the process of doing a flame test.

Usually the water will contain some dissolved minerals, which include calcium and sodium ions. Sodium ions even in small amounts can strongly colour flames to be orange/yellow. The colour produced by calcium (redish), will be masked by the yellow produced by the sodium.
