Abstract
We demonstrated control of structural color visibility using colloidal particles covered with a catecholic polymer shell layer. When exposed to ammonia vapor, the pellet sample obtained by assembling the particles extended the conjugated length of the shell polymer, giving the particles the ability to absorb scattered light in situ and improving the visibility of structural colors.
