General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0A1590, is a deep blue pigment originally derived from the gemstone lapis lazuli. The name 'ultramarine' comes from the Latin 'ultramarinus', meaning 'beyond the sea', as the pigment was imported to Europe from mines in Asia and Africa. This color is known for its rich, intense hue and has been prized by artists since the Middle Ages. In the RGB color model, #0A1590 consists of 3.92% red, 8.24% green, and 56.47% blue. In the CMYK color model, it is composed of 93% cyan, 85% magenta, 0% yellow, and 44% black. Ultramarine is often associated with royalty, wisdom, and spirituality. Today, synthetic ultramarine is widely available, offering a more affordable alternative to the natural pigment while retaining its striking color characteristics. It has a significant presence in art and web design.

The color #0A1590, a deep ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low contrast ratio when paired with darker shades, potentially making text or interface elements difficult to read for users with visual impairments. To ensure inclusivity, it's crucial to use this color with light backgrounds like white (#FFFFFF) or very light grays. Tools like contrast checkers can verify compliance with WCAG (Web Content Accessibility Guidelines) standards. Furthermore, avoid relying solely on color to convey important information; supplement it with text labels or icons. When using #0A1590 for interactive elements like buttons, provide sufficient visual cues for hover and focus states to aid users who navigate with keyboards or assistive technologies. Careful attention to these details will create a more accessible and user-friendly experience for everyone.
