General Information about Ultramarine

The hex color #180492, also known as Ultramarine, is a deep shade of blue that belongs to the blue color family. In the RGB color model, it consists of 9.41% red, 1.57% green, and 57.25% blue. This particular combination results in a color that is often associated with depth, stability, and intelligence. Ultramarine has historical significance, as it was originally derived from the rare and expensive mineral lapis lazuli. This explains why, throughout history, ultramarine has been highly valued in art and decoration. Today, synthetic pigments have made it more accessible, but its rich, saturated tone continues to be admired and widely used across various creative fields for its ability to evoke a sense of sophistication and depth.

The color #180492, a deep ultramarine, presents some accessibility challenges, especially concerning text legibility. When used as a background, it demands light-colored text to ensure sufficient contrast, ideally white or a very pale shade of yellow or green. A contrast ratio of at least 4.5:1 is recommended for body text and 3:1 for larger text elements according to WCAG guidelines. For users with visual impairments, including color blindness, relying solely on color to convey information is not advisable. Supplementing color with text labels or icons is crucial. The use of this color should be carefully considered in interactive elements like buttons or links, ensuring that hover and focus states are clearly distinguishable, often through a change in brightness or the addition of an underline or border. Careful planning is important to make content accessible and inclusive.
