色彩心理学

True cyan sits at the boundary of blue and green in the visible spectrum, projecting futurism, precision, and digital innovation. It is a primary color in CMYK printing and RGB displays, giving it a distinctly technological identity. Cyan suggests cutting-edge thinking and clear communication.

Design Usage

Medium cyan is a staple in tech branding, cloud computing services, and developer tools. It works well for interactive elements, link hover states, and data visualization highlights. Because cyan is highly saturated, use it as an accent rather than a dominant color to avoid visual strain.
