Letter is a private-banking platform that reads like a gallery exhibition for high-net-worth finance. The visual system pivots between a deep ink-black hero stage and a bright editorial body, with 3D metallic and prismatic renders as the recurring sculptural accent. Typography is split into two deliberate registers: a wide grotesque for interface text and navigation, and a high-contrast serif at 80px for headlines that read like magazine cover titles. Color is used as architectural punctuation — three near-gray tinted panels (peach, mint, lavender) act as gallery walls, while teal, violet, and blue claim the action buttons as discrete brand moments. Components are square and confident: 2px corner radii, generous horizontal button padding, and zero decorative shadow — the renders and typography do all the emotional work.

Hero background, dark surface stage, dark card panel — deep near-black with the faintest blue chill, warmer than pure black but harder than charcoal
Muted helper text, secondary metadata, low-emphasis labels — a true middle gray with no chromatic bias
Borders, dividers, card outlines, button strokes at low contrast — barely-there separators that define structure without drawing the eye
Soft section background, subtle card surface, secondary canvas — sits one step below pure white without grayness
