Distribution of color samples

A machine-readable medium storing instructions which when executed by a processor cause the processor to:

• obtain 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;
• identify a portion of a color space which is non-uniformly sampled by the colors of the generated color samples;
• and
• determine a new sample generation instruction corresponding to the identified portion, the new sample generation instruction being to replace a sample generation instruction in the initial set of sample generation instructions to determine a modified set of sample generation instructions, wherein the new sample generation instruction is generated to increase a uniformity of a distribution of colors in a second plurality of color samples generated using the modified set of sample generation instructions.

Processing circuitry comprising:

• a distribution module to determine a distribution of colors of generated color samples in a first color space, wherein the color samples are generated using a set of sample generation instructions;
• an analysis module to identify anomalies in the distribution of the colors of the generated color samples;
• and
• an instruction generation module to generate a new sample generation instruction when the determined distribution comprises an anomaly, wherein creating a new sample generation instruction comprises modifying a sample generation instruction of the sample generation instructions which contributes to the anomaly.
