Why this page shows fewer blocks

#3A3A3A belongs to the Greyscale Color Family, and greyscale colors have no hue. Hue is an angle on the color wheel, and that angle only exists when a color leans toward one primary more than the others. Here all three channels are equal (R = G = B), so there is nothing to lean and no angle to measure.

Everything built on rotating that angle therefore has nothing to rotate. A complementary color is the hue 180° away — for a grey, that is the same grey. The same goes for analogous, triadic, tetradic and square harmonies. Rather than show seven identical swatches, the register leaves the Hues variation strip and the whole Harmonies section out.

What remains is everything that depends on lightness rather than hue. Tints, shades and tones still work, because they move the color up and down the scale instead of around the wheel. So do the nearest named colors, the conversions and the adjacent color codes.
