This combines a saturated multi-hue spectrum (electric yellow, magenta, lime, cyan and their tints) with a full cool-gray neutral ladder from near-white to ink, giving both expressive accents and a structured UI grayscale. It is well suited to a complete product design system where bright category colors sit alongside neutral surfaces, borders, and text. The caveat is the sheer count of swatches, which demands disciplined token naming so the brights are used as accents rather than fills.
