This image is an attempt to have a smooth gradient transition with the primary colors obvious in the thumbnail rather than a pastel look like the other images it was inspired by, such as '256x256x256', 'Color Corners', or 'All Colors' combined with 'Psychedelic Grid' or 'Are They Parallel?'. It is effectively a row sorted version of 'Juxtaposition of Blue Color Levels Square on Red-Green Color Levels Array'.
