Black is. There was a black flame found on the moon a while back that had the most energy recorded.

Blue
Blue photons contain the highest energy among visible light photons. The energy of a photon is directly proportional to its frequency, and blue light has a higher frequency than other colors in the visible spectrum.
Blue has the highest energy among the colors listed, followed by yellow, red, and green. This is because blue light has a shorter wavelength and higher frequency compared to the other colors.
The visible light with the highest energy corresponds to light in the violet/blue region, which has a wavelength range of approximately 400-450 nanometers.

A few blue chip stock that pays the highest dividends are American Capital Agency, Southern Copper, and NuStar Energy L.P.
Each photon of blue light has more energy than a photon of any other color, because the blue ones have the highest frequency.
The colors of the visible spectrum from highest to lowest energy level are: violet, blue, green, yellow, orange, and red. Violet has the highest energy level, and red has the lowest energy level among the visible colors.
The visible light with the highest frequency (shortest wavelength) carries the most energy. That means it is the light at the violet end of the 'rainbow'. Since the wavelength of violet light is very roughly half the wavelength of red light, a beam of violet light carries roughly double the energy of a beam of red light with equal intensity. In the particle world, a violet photon has double the energy (and double the momentum) of a red photon. We know from (E=H times nu) that energy is directly proportional to the frequency.
The colors of the spectrum going from lowest energy to highest energy are violet, indigo, blue, green, yellow, orange, and red.
Photons with higher energy correspond to electromagnetic radiation with higher frequency/shorter wavelength. In the visible band, the color with the highest frequency is the last one you can see on the VIOLET end of the spectrum.
