We prepared porous polymer gels using a colloidal crystal as a template. The porous structure endows a structural
color to polymer gels. We found that the peak position of the reflection spectra from the porous gels (λmax) is
expressed as a function of the swelling degree, and is synchronized with the change in the swelling degree. We can
estimate the linear expansion factor α of the subchains by comparing the peak position at a given situation (λmax)
and the reference state (λmax, 0), in which the subchains behave as Gaussian coils. Creating the periodically ordered structure, which is similar in size to the wavelength of optical light, in the gels allows us to determine the behavior of polymer chains by observing the structural color.
