Aggregate sets the weight of the palette in neutrality and balance, and Deep Shadow is the swatch that breaks rank: a single black that stops the set reading as one note. Deep Shadow to Sky Concrete spans 71 points of lightness, so the palette can carry its own hierarchy without reaching for a second one. Saturation averages 5 percent, so close to grey that Sky Concrete reads as a colour accent purely by being the least grey thing present.

Aggregate is true neutrality, balance and restraint, a color that recedes so the palette's other choices can carry the emotional weight.
Weathered is true neutrality, balance and restraint, a color that recedes so the palette's other choices can carry the emotional weight.
Sky Concrete functions as quiet breathing room, understated, unobtrusive, built to let other colors do the talking.
