In case of visible spectrum, violet has got least wavelength and hence highest frequency. The energy of light photon is given by the expression E = h nu
where nu is the frequency. Hence violet has got maximum energy per photon.
That is why, in case ordinary oven, where we use fire wood, the flame colour would be yellow or orange. That means the heat content will be less. But in case of kerosene stove or gas stove using the proper design of the burner, the colour of the flame would be blue or violet. Hence the heat content becomes more and cooking is done in shorter duration.
the color spectrum
it can behave like a particle and like a wave (a photon and the E.M spectrum) are the dual properties of light.
I suspect you mean the color with respect to light. If this is the case then red light has the lowest energy of the visible spectrum. Of course visible light is just a small part of the electromagnetic spectrum, for example, infrared light has even less energy. The lowest energy would be found in radio waves. Also it is important to realize that color is just a convention, it has no real physical meaning. Some other animal might see totally different colors.
The color red has the longest wavelength of all the colors in the light spectrum.
The violet light has more energy than the red light. Red light is lower on the electromagnetic spectrum, meaning it has a lower frequency (or longer wavelength). You'll recall the colors of the rainbow as red, orange, yellow, etc., and these are the colors going up the frequency spectrum. Photons higher on the spectrum are higher in frequency and energy.
Each photon of blue light has more energy than a photon of any other color, because the blue ones have the highest frequency.
Different frequincies of light cause color, but a photon can not have color because it is only a single particle of light
A photon's energy is directly proportional to its frequency (inversely proportional to its wavelength).In any given interval of the spectrum, the highest frequency (shortest wavelength) carries the most energy.For visible light, that corresponds to the violet end of the 'rainbow'. The last color your eyes can perceiveat that end is the color with the most energy per photon.
light is given off by an atom when and electron moves from one shell to a lower shell and a specific amount of energy is released in the process (known as a photon). If the wavelength of the released photon are in the spectrum of visible light, we will see it as a specific color based on the wavelength of the photon.
the color spectrum
it is a set of lines corresponding to photon emission wavelengths.
it can behave like a particle and like a wave (a photon and the E.M spectrum) are the dual properties of light.

High-energy photons correspond to short-wavelength light while low-energy photons correspond to long-wavelength light. In short, the answer is red. For short-wavelengths (high energy photons) it would appear blue.
It is called Visible light Spectrum.
The typical green/yellow wavelength (in about the middleof the visible color spectrum).
The color red has the longest wavelength of all the colors in the light spectrum.
