(American Chemical Society) Structural colors, like those found in some butterflies' wings, birds' feathers and beetles' backs, resist fading because they don't absorb light like dyes and pigments. However, the iridescence that enhances their beauty in nature is not always desirable for some applications, such as paints, color displays or printer inks. Now, researchers have developed a new method to produce structural colors that don't change with the angle of viewing. They report their results in ACS Omega.
