Rivian

This system evokes a sense of understated power and refined utility, much like the vehicles it represents. It balances a strong, nearly achromatic palette with crisp typography and subtle interactive accents. The aesthetic is anchored by deep blacks and bright whites, creating high contrast that feels purposeful rather than stark, while carefully articulated letter-spacing at larger type sizes adds a layer of precision. Rounded corners are reserved almost exclusively for interactive elements, softening points of engagement within an otherwise clean, angular visual language. Prioritize 'Adventure' font for all text, applying specific letter-spacing for display sizes 20px and above, ensuring a precise, technical feel. Use Midnight Ink (#000000) for primary text on Arctic White (#ffffff) backgrounds, and Arctic White (#ffffff) text on Midnight Ink (#000000) backgrounds for maximum contrast and readability. Apply a 40px border radius to all primary and secondary buttons, crafting an approachable, modern form factor. Employ the Sunbeam Yellow (#ffac00) as the high-visibility accent color for primary call-to-action buttons, creating a deliberate focal point. Maintain minimal padding within cards (0px), allowing content to define its own space and emphasizing a clean, unadorned aesthetic. Utilize dark backgrounds like Dark Forrest Gradient or Abyss Blue Gradient for hero sections to create a premium, immersive brand introduction. Incorporate subtle, desaturated background colors like Ash Concrete (#e5e7eb) and Cloud Drifter (#f2f2f2) for section separation while maintaining visual lightness. Do not use box-shadows for elevation; rely on color shifts between surfaces to indicate depth, maintaining a flat, modern impression. Avoid generic border radii; use the specified 40px for buttons and 4px for inputs, reserving other radii sparingly for specific elements. Do not introduce additional vibrant hues beyond the established accent colors (Sunbeam Yellow, Forest Green, Desert Orange, Ocean Blue), maintaining the sophisticated monochromatic base. Refrain from heavy text ornamentation like underlines or excessive bolding; the type scale and precise letter-spacing are sufficient for visual hierarchy. Do not use generic system fonts; 'Adventure' is critical for brand identity, with 'Liga' for monumental statements and 'Sohne' for microcopy. Do not use static header navigation on lighter body content; ensure it appears on a dark background or with an appropriate transparent overlay to match the brand aesthetic. Avoid cluttering card or section backgrounds with gradients – use them strategically for dramatic full-width hero or major content blocks only.
