Surface Dark sets the weight of the palette in authority and restraint, and Primary Purple is the swatch that breaks rank: a single purple that stops the set reading as one note. Surface Dark to Surface spans 87 points of lightness, so the palette can carry its own hierarchy without reaching for a second one. Error Pink and Primary Purple sit on opposite sides of the temperature line, which is the tension the palette runs on and the pair to hold apart.
Surface Dark is black's softer relative, still authoritative, but with enough warmth to feel considered rather than severe.
Primary Purple a saturated violet or amethyst: creativity and luxury with real confidence.
Secondary Teal a bright turquoise or peacock teal: tropical, confident, unmistakably alive.
Error Pink carries urgency and appetite, the color the eye finds first.
Surface reads as purity and openness, the color of empty space, clarity, and things left deliberately unresolved.
Zero dimension, bold fills, and geometric clarity - the design language that stripped the digital world of its shadows and gradients
