Abstract: In an example, a method includes obtaining, at a processor, data indicative of a color of each of a first plurality of generated color samples, wherein the color samples are generated using an initial set of sample generation instructions. It may be determined, by a processor, if a spatial distribution of the colors of the generated color samples corresponds to a predetermined spatial distribution in a first color space. When the spatial distribution of the color of the generated color samples does not correspond to the predetermined spatial distribution, the method may further comprise determining, by a processor, a new sample generation instruction. The new sample generation instruction may replace an initial sample generation instruction in the initial set of sample generation instructions to determine a modified set of sample generation instructions. The new sample generation instruction may be generated to increase a correspondence of the spatial distribution of colors of a second plurality of color samples generated using the modified set of sample generation instructions to the predetermined spatial distribution.

Abstract: A method comprises obtaining at a processor a first color gamut and a second gamut represented in a first color space. The first and second gamuts are represented as first and second objects in a second color space, with each object comprising a plurality of nodes. For each node, an index is provided indicating a position in the first color space to which that node corresponds. A further index is provided indicating a position, in the first color space, of the node relative to at least one other node of the object to which the node belongs. Each node of the first object corresponds with a node of the second object providing a mapping between the objects, using the further index. The index of at least one of the first object nodes is adjusted based on the corresponding node of the second object producing a mapping between the gamuts.
