Structural colors are common in natural materials and organisms, suggesting biomimetic approaches. Here, two recent approaches related to structural colors are presented. Classically, block copolymers in the solid state allow well defined periodicities towards well defined structural colors and even their switchings. We show solution-based micellar block copolymeric tunable structural colors facilitated by Coulombic repulsions between the micellar cores. On the other hand, white brightness is shown in nanocellulose random colloidal networks in films of micrometer thicknesses due to anomalous light transport.<br/> <br/>
