Color Characteristics
Cyan sits between blue and green, evoking lakes, glaciers and the early morning sky. Clear and tech-savvy, it performs especially well in tech branding and summer themes. Specifically, Opal Iridescent Blue has a lightness of 70% and a saturation of 100%, bright and airy, ideal as a light background or accent color that creates a soft, comfortable atmosphere; moreover, its saturation is extremely high and its visual tension is strong, so it works best used sparingly as a focal accent. In a word: The blue iridescence of opal's play of color, translucent in tone and full of liveliness.
Color Psychology
Cyan can evoke freshness, calm and trust, with a marked calming effect; psychologically it symbolizes purity, professionalism and technology. For this reason Opal Iridescent Blue tends to leave a first impression of being fresh and pure in the viewer’s mind, and this emotional tone also defines the role it plays in design.
Best Uses
Cyan suits tech products, summer themes, cleaning and care products and any scene that needs a fresh, modern feel. In real projects, Opal Iridescent Blue is also often used as a light background or supporting negative space; in “Cyan”-themed designs, the adjacent colors or lightness gradients built around it quickly establish a cohesive, clearly layered color scheme.
