No, yellow is hotter. The progression, from least hot to hottest, goes: black-red, dark red, bright red, light red, orange, yellow, blue, white-yellow, white.

Give two reasons why the yellow flame is safer on busen burner?
A blue flame is hotter than a yellow flame simply because a blue flame has more oxygen to create extra energy,while red flames have less oxygen to create heat.
Is green fire hotter then blue fire?
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.
What is the surface temperature of a yellow star?
blue is hotter than red and yellow but yellow is hotter than red.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
What color flame has the coolest temperature?
I'm not an expert, but I think it depends on what you're burning, if it is a gas fire than a lazy yellow flame is the coolest. But if you're burning carbons, (paper, charcoal, etc.) than a greenish flame is the coolest.
How hot is the yellow flame?
yes, they are. here are the flame colors in order from hottest to coolest. white - hottest blue - hotter yellow - hot orange - cooler than yellow red - cooler than all of above

Is red hotter than orange in flame colors?
Orange flames are ho
What is a clue to a stars temperature?
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
What is more powerful a red flame or a blue flame?
blue flames are hotter
Why is the blue flame hotter than the red flame?
This isn't necessarily true. It depends on WHY the flame is blue. However, it is true that in order for black body radiation (aka cavity radiation) to appear blue, the object it's coming from must be significantly hotter than an object from which the cavity radiation appears red. Blue light has a shorter wavelength (and therefore a higher energy) than red light, so it requires a hotter object for the blue wavelengths to predominate.
Are yellowed colored stars cooler than red colored?
No. Yellow stars are hotter than red stars.See related question.
Is a star that emits mostley yellow visible light hotter than a red star?
Yes.
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
What is the surface temperature of a yellow star?
blue is hotter than red and yellow but yellow is hotter than red.
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.
