A spectrometer.
A spectrometer, or your eyes. Each color is a different wavelength, if you learn what the wavelengths are for different colors, eventually, you can estimate fairly accurately by sight. In order to identify color, you need a spectrometer and another information source. The information source would be a listing of wavelengths that correspond to a color. In chemistry, you cannot just use your eyes to determine a color, because color is an opinion that can vary between people. Instead, you use the spectrometer to find the wavelength, then determine what color the light is using a wavelength/color chart. The visible light spectrum is between 400nm - 700nm. A good chart and background info is: <http://www.cem.msu.edu/~reusch/VirtualText/Spectrpy/UV-Vis/spectrum.htm>
A spectrometer measures the intensity of light at different wavelengths, providing detailed information about the composition of light. A colorimeter, on the other hand, measures the color of light by comparing it to standard colors. Spectrometers analyze light properties by breaking down light into its individual wavelengths, while colorimeters focus on the overall color of light.
This is a spectrometer.
A device that breaks light into colors and produces an image is a spectrophotometer or a spectrometer. These instruments measure the intensity of light as a function of its color or wavelength.

Green and silver do not create a new color when combined. Instead, they maintain their individual characteristics – green remains green and silver remains silver.
A colorimeter measures the intensity of a specific color in a sample, while a spectrometer measures the entire spectrum of light. Colorimeters are used for simple color analysis, while spectrometers are used for more detailed analysis of substances based on their light absorption or emission properties.
The colors red, orange, and white do not mix to create a specific new color. Instead, they retain their individual hues when combined.

Instead means in place of something, so you could say, instead of the color blue, I like the color green.
The difference between the photometer and the spectrometer is a matter of complexity. Both are used to measure color absorbency quantitatively, but photometers are much simpler in design, having fewer parts, and as such are less expensive and easier to obtain. They're usually not quite as detailed in results as a spectrometer, however.
