Design System Inspiration of Kraken

1. Visual Theme & Atmosphere

Kraken's website is a clean, trustworthy crypto exchange that uses purple as its commanding brand color. The design operates on white backgrounds with Kraken Purple (#7132f5, #5741d8, #5b1ecf) creating a distinctive, professional crypto identity. The proprietary Kraken-Brand font handles display headings with bold (700) weight and negative tracking, while Kraken-Product (with IBM Plex Sans fallback) serves as the UI workhorse.
