Fabrication of motheye‐like colloidal surface patterns as an antireflection coating is presented. Using layer‐by‐layer assembly and a novel colloid‐on‐colloid stamping strategy, snowman‐like patterns consisting of different‐sized colloids were fabricated (see Figure). The pattern spacing and height can be easily tailored by varying the salt concentration and the number of colloidal layers attached, respectively.
