what is the actual colour of fire ? is it like blue or red or orange or yellow or what ?

Answer 1

It varies according to what is burning and also on such things as the oxygen supply. Hydrogen for example burns with a blue flame.

Answer 2

Fire is the forth state of matter - a plasma. The colour comes from the electrons recombining with the ions. The light emitted depends on the material in the plasma. So in answer to you question - it depends. Sodium has a very bright yellow recombination line and is common in the kinds of materials we find burning, which is why fire looks mostly yellow.

Answer 3

It varies depending on temperature of flame and what is burning, I've even seen purple and green flames when burning plastics. Usually fire is red orange yellow and sometimes a bit blue

Answer 4

It depends on its fuel. Here are two examples:
1. Wood = a yellow/orange flame
2. Gas (from say British Gas) = a blue flame

Answer 5

It depends what is burning and how hot it is burning. Wood Burns yellow, orange, red. Newspaper color ink burns green and blue. Alcohol burns with no visible flame as does nitrogen. And liquid gas burns blue.

Answer 6

i 've been thinkign of that lately too cos i wanted to paint fire and i quite couldn't because..i don't exactly knwo the colours so thx for postign up the question..but i've also been thinking..i know that oxygen in need for fire to burn but are the reactions right before a fire start? oxygen doesn't hurt us nor does the wood(unless u get hit by it) but when they lit up..it burns us...how does that happen? atoms the smallest matter right? what's for fire then?

Answer 7

It depends on the material which is burning. when any material burn it's electron take energy from the heat and it's electron is excited and jump to next orbital and releases electro magnetic wave of certain frequency (colour).. the colour of the flame depends on the initial and final orbital of the electron of the material during burning..that's why hydrogen gives blue flame.

Answer 8

it is the reddish yellow. but as yellow and red make orange it appears orange ...and there is blue color in inner region because no oxygen reaches to it.... so the colour are orange,red,yellow and blue.

Answer 9

It can be any color.

Blue for the oven.
Red and Yellow for the fire place.
Orange for a torch.

There are many differnt types. There's even green fire. Although I can't remember what it's called.

Answer 10

depends how hot it is and how much oxygen it has, usually starts off an orange colour, then gets white in the middle as it gets hot, and if it gets really hot it'll go blue in the middle.
