TL;DR
Cal.com employs a "monochrome-plus" aesthetic where the interface is almost entirely achromatic (#ffffff, #111111, #242424) until a functional action or link is required. The primary brand accent is a high-saturation blue (#0000ee), used exclusively for interactive text and specific UI highlights. Typography is the primary brand carrier, pairing the geometric character of **Cal Sans** for headlines with the utilitarian clarity of **Inter** for UI controls. Layouts are governed by a strict 4px base unit, utilizing generous 64px and 80px vertical rhythms to separate major content blocks.
