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 weakest color of light is typically red, as it has the longest wavelength and lowest energy in the visible light spectrum.
Violet has the shortest wavelength and highest frequency among visible light colors, whereas red has the longest wavelength and lowest frequency.
Violet light has the lowest wavelength in the visible light spectrum.
546nm light wavelength corresponds to a green color.
Color light waves differ in terms of their wavelength and frequency. Each color corresponds to a different wavelength within the electromagnetic spectrum. For example, red light has a longer wavelength and lower frequency than blue light. This difference in wavelength is what gives each color its unique appearance to the human eye.
That's blue light.
Red color will have the longest wavelength, which corresponds to the lowest energy in the visible light spectrum.
The weakest color of light is typically red, as it has the longest wavelength and lowest energy in the visible light spectrum.
Violet has the shortest wavelength and highest frequency among visible light colors, whereas red has the longest wavelength and lowest frequency.
Violet light has the lowest wavelength in the visible light spectrum.
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.

For example, red light has a longer wavelength and lower frequency than blue light. This difference in wavelength is what gives each color its unique appearance to the human eye.
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.
The visible light with the shortest wavelength is the last color you can see on the blue/violet end of the rainbow. It's not exactly the same for all eyes.
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.
The visible light with the shortest wavelength is the last color you can see on the blue/violet end of the rainbow. It's not exactly the same for all eyes.
