We create colloidal crystal assemblies over large areas containing up to 4 different functionalised polystyrene and silica particles. The method utilises evaporation induced self-assembly from colloidal suspensions confined on a hydrophilic surface. The morphology of the crystals is tuned by the particle size ratio employed during assembly.
