Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.
Violet light has the highest energy.
The color red is the longest wavelength in the visible light spectrum because the less energy a wave carries the longer the wavelength and red carries the least energy of all the colors in the visible spectrum
Red light.
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.
a broader spectrum of visible light energy can be used for photosynthesis

Red, I believe.
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 highest frequency/shortest wavelength of visible light isthe last color you can see on the blue end of the spectrum.

The typical green/yellow wavelength (in about the middleof the visible color spectrum).
Of the visible light spectrum, that would be blue light.
