/[RGB][0369CF]/ is a collectable set of eighteen 6x6 color grids, each piece representing a unique 1/6 subset of the 6^3 color space. Every constituent color is defined by a solitary block. At large display sizes, local contrast optical illusions begin to produce the perception of false gradients. Roughly 2 kilobytes per piece. (600 x 600, 2021)
