About Ultramarine

Ultramarine, represented by the hexadecimal color code #191289, is a deep and vivid shade of blue. Historically, ultramarine was a highly prized pigment made from ground lapis lazuli, a rare and expensive gemstone. This made it a color reserved for royalty and religious figures in art. Today, synthetic ultramarine is widely available, offering the same rich hue at a fraction of the cost. In color psychology, ultramarine is often associated with feelings of calmness, trust, and intelligence. It is frequently used in branding and design to convey a sense of stability and authority. The color is very prominent in various contexts, from corporate branding to artistic expression, indicating its versatile and enduring appeal.

The color #191289, a deep ultramarine, presents some accessibility challenges. Its dark hue results in a low contrast ratio against lighter backgrounds, potentially making text or interactive elements difficult to read for users with visual impairments. To ensure accessibility, it is crucial to pair this color with significantly lighter shades for text and interactive components. White or very light yellows and greens would provide sufficient contrast. Using tools to check color contrast ratios is highly recommended to meet WCAG (Web Content Accessibility Guidelines) standards, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Moreover, avoid using this color as the sole indicator of functionality; always provide additional cues such as labels or icons to ensure inclusivity for all users.
