Kraken

Design System Inspired by 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.

Key Characteristics:

• Kraken Purple (#7132f5) as primary brand with darker variants (#5741d8, #5b1ecf)

• Kraken-Brand (display) + Kraken-Product (UI) dual font system

• Near-black (#101114) text with cool blue-gray neutral scale

• 12px radius buttons (rounded but not pill)

• Subtle shadows (rgba(0,0,0,0.03) 0px 4px 24px) — whisper-level
