Abstract: In some examples, a print cartridge includes a memory device comprising quantized coefficients derived from a compression of a difference table including a plurality of difference nodes in which each difference node represents a value that is a difference of a value of a node of a color table and a value of a corresponding node of a reference table, the quantized coefficients useable to produce a reconstructed difference table, and a plurality of residue nodes in which each residue node represents a value that is a difference of a value of a node of the color table and a value of a corresponding node of the reconstructed difference table.

Abstract: In some examples, a supply component for a printing device includes a memory device comprising corrective data to produce a customized color table for a first color gamut, wherein the corrective data corresponds to nodes of a reference color table for the printing device that is able to employ a plurality of color gamuts for printing. The corrective data comprises a plurality of residual values to transform the nodes of the reference color table to the customized color table. The corrective data is accessible by the printing device to transform the reference color table to the customized color table used for printing to a media using the first color gamut.
