    • A colored platelet 10 comprises: a substrate 12, preferably formed of glass, silicon oxide, mica or aluminium oxide; an adhesion layer 15 which surrounds the substrate 12; and a colour pigment layer 18, wherein the colour pigment layer includes colour pigments that are attached to the adhesion layer 15. Preferably the adhesion layer 15 is an aminosilane monolayer selected from the group including 3-(N,N-dimethylaminopropyl) trimethoxysilane, (N,N-dimethyl-3-aminopropyl) methyldimethoxysilane, (dimethylamino) methylethoxysilane, N-n-butyl-aza-2,2-dimethoxysilacyclopentane, bis(3-trimethoxysilylpropyl-N-methylamine, N-allyl-aza-2,2-dimethoxysilacyclopentane, bis(2-hydroxyethyl)-3-aminopropyltriethoxysilane, N,N -bis(hydroxyethyl)-N,N -bis(trimethoxysilylpropyl)ethylenediamine and bis(methyldimethoxysilylpropyl)-N-methylamine. The coloured platelet may further include an oxide layer selected from iron oxide, silicon dioxide, titanium dioxide and zirconium oxide that surrounds the substrate. The coloured platelet may also include a secure layer 25 that secures the colour pigments to the adhesion layer. A method of producing a coloured platelet comprising: dispersing a substrate in a solvent to form a substrate dispersion; adding an aminosilane to the substrate dispersion so as to form an adhesion layer; and adding a colour pigment dispersion to the substrate dispersion so as to form a colour pigment layer is also outlined.
