It takes a little creative interpretation to make this look good, but the use of color mixing really makes a difference. See for yourself in the demo after the break.

Silver nanoparticles trapped within a polymer matrix allow for precise color control in anti-counterfeiting technologyBy trapping silver nanoparticles within a polymer matrix, researchers can manipulate particle size and, consequently, the color emitted under UV light. Larger polymer nets yield silver ...
