General Information about Ultramarine

Ultramarine, represented by the hex code #0b0494, is a deep, vivid blue color known for its rich and intense hue. The name 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally derived from the precious gemstone lapis lazuli, imported from faraway lands. Historically, it was highly valued as a pigment in Renaissance paintings due to its brilliance and permanence. Today, synthetic ultramarine is widely available, offering a more affordable alternative while retaining the color's characteristic depth. In color psychology, ultramarine is often associated with qualities like intelligence, trustworthiness, and depth of feeling. It evokes a sense of calmness and stability, making it a popular choice in various design applications, where it represents an elegant richness.

The hex color #0b0494, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text or interactive elements, it is essential to ensure sufficient contrast against the background. Due to its dark hue, it requires a very light background color to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a color contrast checker is crucial to validate that the chosen color combination is accessible to users with visual impairments. Additionally, avoid relying solely on color to convey information; use text labels or icons to ensure that the content is understandable to all users, including those with color blindness. Consider providing alternative high-contrast themes or allowing users to customize colors to suit their individual needs.
