In the RGB color model, #1A0394 is composed of 10.2% red, 1.2% green, and 58% blue. This high blue component gives the color its distinct depth and intensity. Ultramarine has a long history, dating back to ancient times when it was derived from the gemstone lapis lazuli. The name "Ultramarine" literally means "beyond the sea," reflecting its origin as a pigment imported from distant lands. It has been prized for its vibrant color and was often used in religious art and royal decorations. Today, synthetic Ultramarine is widely available, making it more accessible for various applications.

The hex color #1A0394, a deep shade of Ultramarine, presents considerable accessibility challenges, especially in web design. Its dark nature results in low contrast against lighter backgrounds, which can make text or interactive elements difficult for users with visual impairments to discern. According to WCAG guidelines, sufficient contrast is crucial for readability. To ensure accessibility, it is recommended to pair #1A0394 with very light colors, such as white or very pale yellows, to achieve a contrast ratio that meets at least the AA standard. Avoid using it with mid-tone or dark colors, as this will almost certainly fail accessibility checks. When using this color for interactive elements, consider providing additional visual cues, such as underlines or borders, to enhance usability for all users. Testing with accessibility tools is highly advised.
