Expanding the plasmonic painter’s palette

By blending paints in their palette, artists can
create a broad spectrum of colors with subtly different hues.
However, scientists who wish to create a similar range of
structural colors, like those found on butterfly wings, are much
more limited. Now, researchers reporting in ACS Nano have developed
a new method for mixing plasmonic red, blue and green to yield a
virtually unlimited number of colors that could be used for new
types of displays.
