Across 512 indexed artworks, the grids carry 12,498 color blocks (about 24.41 blocks per schema on average).

Most of that surface area is two swatches per block: 11,283 blocks use a pair, which is why duos and gradients feel like the default language of the collection. Only a few hundred blocks stretch to three or more swatches.

Ramps carry most of the load: 9,512 blocks (well over three quarters of the set) use a ramp-led treatment. Pure glow shows up on 1,576 blocks, glow-and-ramp hybrids on 953, and a smaller group of 457 reads as solid fills. Those four styles partition the entire surface count.
