At 1670 K (1400 °C), blue is the hottest part of the flame. Then red(1070 K, or 800 °C), orange and yellow, as you move away from the center of the flame to the outer edge. See Link 1 below.
The reason for this is explained in both links below. Different colors within the flame are caused by the excitation of electrons, and the particular amount of photons emitted as a result of the "activity." The 2 links below explain this process more thoroughly.

Not sure what you mean by stronger, but blue flames are definitely hotter than yellow flames. That's why when you look at a fire, close to the wood (which is hotter) is usually blue, while the top of the flames are yellow.

Have you ever noticed in the night sky the different colors of the stars? Some will be shining slightly red, some blue, some white. The hottest of stars look blueish, while the expanding and dying stars look a little red. Our own sun is yellow, in between the two extremes. A flame is similar. The bluer flame is the hotter flame.

I'm not sure what you mean is stronger, but a blue flame is generally hotter than a yellow flame.

Not stronger, but it is a lower temperature than blue flame. Blue is hotter than a yellow flame.

The blue flame is hotter than the yellow by about 120 degreese :]
hope it helps

The sunlight is termed a black physique. Black bodies emit EM radiation based upon absorption and dissipation. They persist with the Wien's displacement regulation. The sunlight emits all wavelengths of the EM spectrum yet quite often yellow seen easy measured at 550nm on the EM spectrum. by using applying this recommendation, we are waiting to be certain the temperatures of incredibly some stars alongside with our own. a megastar produces warmth and lightweight interior the path of the technique of nuclear fussion. this isn't comparable to a flame. A flame desires 2 issues to accomplish in a combustion- a chemical to burn and an oxidizer. The oxidizer is oftentimes oxygen yet would be different chemical compounds. Non-black bodies (flames) persist with a various regulation noted as Kirchoff's regulation. the colour of flames are dependant upon the chemical being combusted and the fee of combustion. All flames are in essence blue yet diverse chemical compounds will produce diverse colorings. This explains fireworks. If we glance heavily at any flame, the backside of the flame is blue. This represents finished combustion of the textile being burned. added up the flame, the textile is not being effectively oxidized. We see incomplete combustion through fact the molecular debris of the textile are escaping without being burned.

Blue flame is hotter white the hottest think of a cutting torch.

No yellow flame is not hotter than blue. Blue is hotter.

define "stronger"?. A blue flame is hotter and more resistant to change.
