Психология цвета
Pure red is the color of adrenaline, passion, and urgency. It raises heart rate and stimulates appetite, which is why fast-food chains and sale banners rely on it worldwide. Culturally, red signifies luck and prosperity in East Asia while representing danger and prohibition in Western road signage.
Design Usage
Medium red is ideal for call-to-action buttons, sale badges, and notification dots where instant attention is needed. It should be used sparingly as an accent rather than a dominant background to avoid visual fatigue. Red pairs effectively with white text for maximum legibility in buttons and banners.
