1. A data carrier having a surface, comprising:
a plurality of recesses on the surface encoding information,
wherein the plurality of recesses are grouped in pixels forming an image,
wherein NR+NG+NB predetermined positions are attributed to each pixel, the NR+NG+NB predetermined positions comprising NR predetermined R positions, NG predetermined G positions and NB predetermined B positions,
wherein each pixel comprises between zero and MR recesses located at a subset of zero to MR positions of the NR predetermined R positions,
wherein each pixel comprises between zero and MG recesses located at a subset of zero to MG positions of the NG predetermined G positions,
wherein each pixel comprises between zero and MB recesses located at a subset of zero to MB positions of the NB predetermined B positions,
wherein the number of recesses at the predetermined R positions, nR, of a given pixel defines an intensity of the color red,
wherein the number of recesses at the predetermined G positions, nG, of a given pixel defines an intensity of the color green,
wherein the number of recesses at the predetermined B positions, nB, of a given pixel defines an intensity of the color blue, and
wherein the subset of zero to MR positions, the subset of zero to MG positions, and/or the subset of zero to MB positions of a given pixel defines additional digital information attributed to the pixel.
