Tinted Glass sets the weight of the palette in clarity and freshness, and Steel Dark is the swatch that breaks rank: a single black that stops the set reading as one note. Steel Dark to Daylight spans 88 points of lightness, so the palette can carry its own hierarchy without reaching for a second one. Saturation averages 9 percent, so close to grey that Daylight reads as a colour accent purely by being the least grey thing present.
Steel Dark reads as pure authority: sophistication, power, and the visual weight that makes everything placed near it feel more serious.
Tube is black's softer relative, still authoritative, but with enough warmth to feel considered rather than severe.
Tinted Glass a dusty slate-teal, clarity read through restraint.
Polished functions as quiet breathing room, understated, unobtrusive, built to let other colors do the talking.
Daylight a pale seafoam, teal's clarity turned airy and light.
