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.
Your question is meaningless. Light is electromagnetic radiation and the colour of light depends on the wavelength of this radiation. There is no such thing as a "weak" wavelength.
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.
Each color has a different frequency and wavelength; with red having the longest wavelength and lowest frequency of all the visible colors & violet having the shortest wavelength and highest frequency of the colors humans can see.
That's blue light.
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.
546nm light wavelength corresponds to a green color.
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.
Each color has a different frequency and wavelength; with red having the longest wavelength and lowest frequency of all the visible colors & violet having the shortest wavelength and highest frequency of the colors humans can see.
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.
