We developed a technology for volume color reflection pixels in nanoporous glass (NPSM). This technology is based on direct laser writing (DLW), focused laser (λ =515 nm, P = 83 W, ν = 200 kHz,τ = 220 fs) used to obtain high laser intensity for refractive index modification of NPSM. Green reflection pixels can be observed under the microscope reflection mode. After impregnation of distilled water, the reflective color changes to red. The geometric shapes and spectrum have been tested.
