A spectrograph can do that.

That's called - a prism.
-- The colors of light that the object absorbsare gone, and aren'tavailable to proceed to your eye.-- The colors of light that the object reflectsproceed from the objectto your eye. They are the colors that the object "looks" to you.
reflect
All the colors that are NOT absorbed by the object.

No, the colors you see are the colors that are reflected by the object. White light is composed of several different wavelengths of energy, these different energies correspond to different visible colors. When an object absorbs the light, it absorbs its energy, the rest of the energy is reflected from the surface. That energy is what you see in the form of photons (light). So, if an object looks blue to you, that object is absorbing red light.
any colors that are not part of the color of the object are absorbed by the object. light of the colors that do make up the color of the object are reflected back to your eyes.
If an object absorbs all the colors of light, it will appear to be black. It is the reflected part of the spectrum that gives an object its color.
a spectroscope is a device that breaks up light into a spectrum of colors.
the color of the light it reflects and absorbs. If the object reflects red and absorbs all other colors, the object will appear red.
Prism ...it breaks up light into different colors.
