To mimic this, index matching fluid with different refractive indices were drop coated on isolated Au nano spheres in forms of monomer and dimers. The scattered image was then recorded by color CCD and the sRGB values were converted to CIE 1931 color space. The color difference in response to the corresponding index difference was compared to that obtained by spectrometer.
