3D Printing of Structural Colors

[BillTre]

Browns, Reds, and Blues have been 3D printed (video here) by making very tiny shapes similar to those that underlie the iridescence phenomena.

This kind of coloration is in some ways similar to the another favorite of mine (which I would call a structural non-color): Vantablack (Vertically Aligned NanoTube Array).

Is there a question here?

No, it merely informative.
