Colored projection by multi-lens array projector

A multi-lens optical element comprising:

• a plurality of optical channels,
• wherein each optical channel is defined by a corresponding field lens and a corresponding imaging lens;
• a structured layer configured to define for each optical channel partial projection to be projected via the optical channel to obtain a resulting projection via a superposition of the partial projections from the plurality of optical channels;
• and
• a light coloring layer disposed in at least one optical channel of the plurality of optical channels,
• wherein the light coloring layer is disposed to cover a first portion of the structured layer in correspondence of the at least one optical channel and leave a remaining portion of the structured layer in correspondence of the at least one optical channel free of the light coloring layer, and
• wherein the light coloring layer is configured to impose a predefined color on light passing through the light coloring layer.
