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.

Any shorter than that and it's not visible.

What colour light has the lowest wavelength?
In the "visible" light it is violet.
Which light has the longest wavelength and the shortest frequency?
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
What is the color of light related to?
The color of light is related to its frequency or wavelength.
What determine the color of a light wave?
Its wavelength (or frequency).
Which color light has a longer wavelength?
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
What color of the rainbow has the lowest wavelength?
That's blue light.
Which color will have the longest wavelength which corresponds to the lowest energy?
Red
What colour light has the lowest wavelength?
In the "visible" light it is violet.
In the visible spectrum which color of light has the most energy?
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.
What color of light has the lowest wave length?
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.
What color of visible light has the lowest wave length?
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.
Which color of visible light travels the slowest through a glass prism?
The lowest frequency / longest wavelength of visible light are those of the last color you can see on the RED end of the rainbow.
Which light has the longest wavelength and the shortest frequency?
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
How is the color of light determined?
By the light's wavelength.
Which color of the visible light portion the the electromagnetic spectrum has the lowest frequency and the least energy?
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.
What is the color of light related to?
The color of light is related to its frequency or wavelength.
What color of visible light has longest wavelength?
Red is the longest wavelength of visible light
