General Information about Ultramarine

Ultramarine, represented by the hex code #170BA9, is a deep blue color known for its rich and vibrant hue. Historically, Ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive pigments. The name 'Ultramarine' literally means 'beyond the sea,' referring to its origin from lands beyond the sea. Today, synthetic Ultramarine is widely available, offering the same stunning color at a fraction of the cost. In color theory, Ultramarine is often associated with depth, stability, and wisdom, lending itself to designs that aim to evoke trust and authority. Its use can bring a sense of elegance and sophistication to any design project, whether in digital interfaces, print materials, or even interior design.

The color #170BA9, Ultramarine, presents several accessibility considerations for web design. Its dark hue means it generally requires light-colored text for sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Ultramarine as a background, ensure text meets these contrast requirements to aid users with visual impairments. Tools like contrast checkers can help assess compliance. Moreover, avoid relying solely on color to convey important information, as colorblind users may struggle to differentiate it from other colors. Supplement color cues with text labels or icons. In interactive elements such as buttons or links, provide clear visual cues on hover or focus states to ensure affordance and usability. Thoughtful application of Ultramarine, combined with appropriate contrast and redundant cues, enhances inclusivity.
