This collective oscillation, the surface plasmon, picks a particular wavelength, or colour, out of the incident light, and this determines the colour we see.

When the collective resonance of valence electrons in the noble metal is equal to the frequency of the incident light, dipolar localized surface plasmon resonance (LSPR) is generated [4,5], where the incident wave may excite dipolar LSPRs on the surface of the noble metal NPs.
One characteristic of these plasmons is that they can join with a photon to become a surface plasmon polariton (SPP) which can travel along the surface of the metal until it dissipates its energy in to the metal or through radiation in to the adjoining medium - such as air.
