Assuming we're not throwing ions into the flame and the color is due strictly to temperature, the blue flame is hotter.
The problem is that flames can be different colors for reasons other than temperature. Specifically, they may contain ionized materials with strong emission lines that color the flame. Probably the easiest example to observe using ordinary household materials is sodium which gives an orangish yellow color (easily seen by dropping a few crystals of table salt into the flame of a gas stove).
The reason that hotter flames are blue is that blue light is more energetic than red light. A hotter flame has more energy, and therefore generates more energetic light.

∙ 13y agoBlue flames are hotter than red flames. i hear theres a such thing as a white flame, it might be the hottest
Wiki User
∙ 13y agoA blue flame is usually much hotter than a yellow or red flame.
Wiki User
∙ 14y agoThe lighter it is, the hotter and more pure it is, so an orange flame is hotter.
After that comes a blue flame, then a white flame.

Why is the blue roaring flame hotter?
actually, the hottest part of a fire IS the blue-green part!
Why is it better to use a blue flame on a Bunsen burner?
It's hot, for one. The Bunsen burner's blue flame is unusual, however, in that it emits little light, so it can be difficult to see under some circumstances.
What is the hotter green flame or blue flame?
Blue. One way to think of it is to consider visible light. Light with short wavelength has high energy (as you move towards purple from red). So for a flame to be producing a certain colour it needs the energy to create this colour. As blue is closer to purple that green is in the visible spectrum, then the flame must have more energy which must mean the flame is hotter.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
How do you heat a test tube with a Bunsen burner?
the advantage of a blue flame is that it is more effecient(hotter flame less flue). the flame is hotter than a yellow one and no soot is produced which blackens test tubes
Is orange fire hotter than blue fire?
No, blue fire is a lot hotter
Is green fire hotter than blue fire?
yes because it could be made with 4 blue fires and it has lot more chemicals

Is blue fire hotter than yellow fire?
yep,
Is yellow fire hotter than blue fire?
yep,
What is hotter green fire or purple fire?
I'd say purple fire
Is blue fire hotter then red fire?
Yes, when you loom at a fire, which color is closest to the fule of the fire is hottest
What color of fire is the hottest?
Technically, all colours of fire are the same temperature, but with colour, they get more condensed/concentrated; for instance, red fire could be as hot as blue fire, but blue fire would appear hotter to the touch because it is more concentrated. Anyway, from least condensed to most it goes: Red, Blue, Green, Purple, White.
Does blue fire mean it's the hottest or coldest or electric?
Blue light is of a higher energy than red light. That means that the fire with the blue light is hotter, as the fire must generally be hotter to generate the blue light. For example, in a gas flame, the blue, which is hottest, is in the middle, and any yellow, orange or red is around the outside.
How color of light is related with surface temperature?
Because,Blue is the hottest light/fire and Red is the less hottest light/fire the bluer the fire/light the hotter it is,The redder it gets,the less hotter it gets from the temperature.
Is a blue flame hotter than 500 degrees Fahrenheit?
Yes, From what i know Red Flames are 1800F...Orange is 2200F... and White is 2700F. I'm Trying to Find out how much it Need for a Pure Blue Fire
