Structural colors based on nanostructured surfaces are an environmentally friendly alternative to dyes and pigments. In this study, structural colors were produced by spherical silica nanoparticles. By controlling the size of the spherical silica nanoparticles, the changes in color were controlled. The sizes of the nanoparticles were controlled by adjusting the ammonia content in the conventional Stöber method. Spherical silica nanoparticle powders were obtained using a centrifuge and an ultrasonic grinder oven, which were s
