General Information about Ultramarine

Ultramarine, represented by the hex code #1B0AAA, is a deep blue color known for its rich and intense hue. Its name 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, ultramarine pigment was highly prized and expensive, often reserved for important artistic commissions, such as depictions of the Virgin Mary in religious paintings. Nowadays, synthetic ultramarine is widely available, making it accessible for various applications. This color evokes feelings of depth, stability, and sophistication, and is frequently associated with trust and authority. In color psychology, blue is often linked to calmness and introspection.

The hex color #1B0AAA, also known as Ultramarine, presents some accessibility challenges, primarily concerning contrast. When used as text, it requires a very light background to ensure readability, ideally a white or near-white color. Due to its dark hue, individuals with visual impairments might find it difficult to discern against darker backgrounds. For buttons or interactive elements, consider increasing the font size or adding a subtle border to improve visibility. Adhering to WCAG (Web Content Accessibility Guidelines) standards is crucial. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against the background is recommended. Tools like contrast checkers can help verify compliance and suggest adjustments. Furthermore, avoid relying solely on color to convey important information; supplement it with text labels or icons to accommodate users with color blindness.
