For a photon of light to cause any action, it must be absorbed. Clear CS does not absorb any light in the visible spectrum at all, so if any change were to be expected it would HAVE to come from interaction with ultraviolet. Now if you have yellow colored CS then the light absorbed is in the violet and ultraviolet spectrum, so the longest wavelength that could affect it wold be violet.
It is very well known how silver compounds at least react with light. This is the basis of almost all photography. The longer the wavelength of the light, the larger the particle has to be normally. Thus film use to not be sensitive to red or infrared light at all. However more modern films have other substances in the emulsion which absorb the light, then pass the energy on to the silver to expose it. This allows modern fine grained films to be sensitive to all colors, and even infrared. Thus it is apparent that for silver activation a resonance is not required, only a minimum quanta of energy.
