Why it works

Rubik's rounded corners give headlines an approachable, product-friendly softness, while Source Sans 3 — Adobe's first open-source family, drawn by Paul Hunt for user interfaces — keeps body copy crisp and unobtrusive. Both have low stroke contrast and open apertures, so they share a legibility-first DNA even though one is playful and one is sober. That balance suits consumer SaaS and ecommerce, where trust and friendliness must coexist.
