We show the angle-independent coloring of noble metals in air arising from nanoparticle distributions on the metal's surfaces. We report the coloring of gold and silver with colors ranging from violet to red. Individual fixed colors are showed to be linked to a total accumulated fluence value. We also show that creation of laser induced gratings on 3 dimensional surfaces.
