    Wouldn’t it be great if you never had to repaint or replace something just because the color faded?

    Wouldn’t it be great if you never had to repaint or replace something just because the color faded?

    A team of scientists from Harvard University’s School of Engineering and Applied Sciences says yes, and feel strongly enough about it to devote their time to making everlasting brilliant hues obtainable.

    They forged a path to success by following birds.

    In particular, the inspiration came from the eternally dazzling blue feathers of the spangled cotinga.

    Commonly used color additives work by reflecting some wavelengths while absorbing others.

    They fade because they’re structurally sensitive to energy and over time, break down and become weak, pale versions of their former selves.

    Bird feathers don’t because their color is structured differently. Instead, the feather’s nanostructure contains spaces within the particles that amplify specific wavelengths to create particular hues.

    The amount of space determines the color that emanates.

    By making capsules of varying particle densities, the scientists say they can create more sound versions of the hues we know and love.

    In addition to being enduring due to their lack of light vulnerability, they are non-toxic.

    The researchers say the method can be used beyond paint and could also better the color performance of displays and flexible plastics.
