Girder Dark sets the weight of the palette in authority and sophistication, and Rivet Steel is the swatch that breaks rank: a single charcoal that stops the set reading as one note. Girder Dark to Saw-tooth Sky spans 79 points of lightness, so the palette can carry its own hierarchy without reaching for a second one. Saturation averages 4 percent, so close to grey that Saw-tooth Sky reads as a colour accent purely by being the least grey thing present.
