The author proposed a method to form colloidal crystal film on a solid substrate in an area over 70cm^2 under silicone oil. In this method, colloidal particles were firstly crystallized in non-closely packed structure. And then the structure changed to closely packing after perfectly evaporating water among the colloidal particles. The author observed the change of structural color of the colloidal crystal film from red (λ=603.5nm) to green (λ=565.7nm).
