Answer 1: Blue flames come from very hot, complete burning of air and fuel. Orange color comes from cooler spots in the flame where fuel isn't being totally burned and these produce a little bit of soot and smoke. The color of the flame is related to the heat of the flame. Think about the colors of different hot things: the Sun is white or yellow, a hot stove is red, a camp-fire is orange, and a gas flame is usually blue. These colors come from different kinds of a light and different places in the electromagnetic spectrum.
Red is the colour of fire. It is the colour of the burning, radiant sun, and of life itself. Both love and anger, joy and wrath are associated with this colour. Red is the color with the greatest power of penetration and will strongly stimulate the flow of blood. It is associated with sex and the first chakra in Eastern spiritual traditions.
