CHROMATIC REFLECTIVE UNIT

In an aspect, a chromatic reflective unit (1) comprises a support structure (7) comprising a plurality of non-coplanar surface sections (7'), a reflective layer (3) formed on the plurality of non-coplanar surface sections (7'), thereby forming a plurality of non- coplanar reflective surface sections (3'), respectively associated with one of the plurality of non-coplanar surface sections (7'), and a chromatic diffusing layer (5) having a back side provided at the reflective surface sections (3') and a front side for being illuminated by incident light (9), wherein the chromatic diffusing layer (5) comprises a plurality of nanoparticles (37) embedded in a matrix (39), and is configured to provide for - together with non-coplanar reflective surface sections (3') - a specular reflectance that is larger in the red than in the blue and for a diffuse reflectance that is larger in the blue than in the red.
