Red, because it has the lowest frequency in visible light
The colors in a rainbow are ordered by their wavelength, with red having the longest wavelength and lowest energy. Thus, red is the lowest-energy color in the rainbow spectrum.
As a solid is gradually heated, the first color to glow and the lowest energy frequency is red. This is because red light has the longest wavelength and lowest energy among visible light colors.
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.
Potential energy is at its lowest when an object is at its lowest point in a system, such as the ground level. This is because potential energy is the energy stored in an object due to its position in a force field, and the lowest point represents the minimum level of stored energy.

Red
The last color you can see at the red end has the lowest frequency,longest wavelength, least energy per photon.The last color you can see at the violet end has the highest frequency,shortest wavelength, most energy per photon.

The colors of the spectrum going from lowest energy to highest energy are violet, indigo, blue, green, yellow, orange, and red.
the color of stars with the lowest surface temperature is red
the color of stars with the lowest surface temperature is red
