Abstract
We present experimental and numerical studies of the color observed from polystyrene colloidal photonic crystals made of 1-4-layers of polystyrene spheres. Simulations allow us to explain the origin of the color we observe under the optical microscope. We show that different colors can be associated unambiguously with different number of layers and type of stacking..
