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.

Why is the blue roaring flame hotter?
The blue roaring flame is hotter because it indicates complete combustion of the fuel which leads to a more efficient release of energy in the form of heat. The blue color is a result of a higher amount of oxygen present in the flame, allowing for a more intense and hotter burn compared to a yellow flame which indicates incomplete combustion.
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.
Why is it better to use a blue flame on a Bunsen burner?
It is better to use a blue flame on a Bunsen burner because it indicates complete combustion of the gas, resulting in a hotter and more efficient flame for heating or sterilizing purposes. A blue flame also produces less soot and smoke compared to a yellow or orange flame.
does metal get hotter if it is near fire and iron?
I think so
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
Is green fire hotter than blue fire?
yes because it could be made with 4 blue fires and it has lot more chemicals
Is orange fire hotter than blue fire?
No, the color of a flame is determined by the temperature at which a material burns. Blue flames are typically hotter than orange flames because they burn at a higher temperature.
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 green fire the coolest temperature of fire?
Green fire is not indicative of temperature. The color of fire is determined by the chemical composition of the fuel burning, not the temperature. Blue flames tend to be hotter than red or yellow flames.
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
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.
Why is the blue roaring flame hotter?
The blue roaring flame is hotter because it indicates complete combustion of the fuel which leads to a more efficient release of energy in the form of heat. The blue color is a result of a higher amount of oxygen present in the flame, allowing for a more intense and hotter burn compared to a yellow flame which indicates incomplete combustion.
What is hoter ''blue or red fire?
Blue fire is hotter than red fire, as the color of a flame is indicative of its temperature. Blue flames typically burn at higher temperatures due to more complete combustion.
What are all colors of fire?
The colors of fire can range from red, orange, and yellow to blue and white, depending on the temperature of the flame. A cooler flame will appear yellow or orange, while a hotter flame will appear blue or white. Other colors, such as green and purple, can also be seen in certain conditions.
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.
