Whenever I read stuff like this I wonder what impact on the design of every day object it will have. A lot of design already looks quite unachievable with technology from 50 years ago but this sounds like it could make a greater shift in that regard.

  New “direct laser writing” set-ups, however, cost about as 
  much as a high-quality industrial 3D printer, and allow for 
  printing at the scale of hundreds of nanometers (hundred 
  to thousand time thinner than a human hair), opening up 
  possibilities for scientists to experiment with structural 
  coloration.

That sounds like some really exciting stuff right there.

Paper here [1].

Two-photon lithography from Nanoscribe [2] is used to make the color-producing nanostructures. This method can make arbitrary 3D structures but currently has a ~100nm resolution limit and is slow---it's quite possible creating the paper's ~1 square mm teapot image took days. It's possible methods like nanoimprint lithography [3] could replicate a fabricated color patch over large areas.

Could this technology have applications for display panels?
