General Information about Ultramarine

The hex color #11019A, also known as Ultramarine, is a deep, saturated shade of blue that evokes feelings of depth, sophistication, and mystery. It belongs to the blue color family and is characterized by its high intensity and slightly purplish undertones. In the RGB color model, it is composed of 6.67% red, 0.39% green, and 60.39% blue. Ultramarine has a rich history, as it was originally derived from the precious mineral lapis lazuli. Because of the labour intensive and expensive nature of extraction of the pigment from the stone, it was highly prized by artists throughout history, especially during the Renaissance. It was often used to depict the robes of the Virgin Mary and other important religious figures. Today, synthetic versions of Ultramarine are widely available, making it more accessible for various applications.

The color #11019A, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low contrast against standard light backgrounds, which can make text and other visual elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is essential for readability. To ensure accessibility, it's crucial to pair this color with very light shades, ideally whites or near-whites, to achieve a contrast ratio that meets or exceeds the recommended levels. Furthermore, avoid using this color for interactive elements like buttons or links without providing clear visual cues and sufficient contrast in their different states (hover, focus, active). Consider offering alternative color schemes for users with specific visual needs to enhance the overall user experience.
