General Information about Ultramarine

Ultramarine, represented by the hex code #08028B, is a deep blue color with a rich history. Originally derived from the precious gemstone lapis lazuli, ultramarine pigment was highly valued and expensive, often reserved for important figures in paintings, such as the Virgin Mary. The name 'ultramarine' literally means 'beyond the sea,' reflecting the pigment's origin from stones imported into Europe from distant lands. Today, ultramarine is synthetically produced, making it more accessible. The color is known for its intense and pure blue hue. In the RGB color model, it's composed of 0.03% red, 0.01% green, and 54.51% blue. Its CMYK values are 100% cyan, 99% magenta, 0% yellow, and 69% black. Ultramarine finds applications in various fields, from art and design to cosmetics and manufacturing.

The color #08028B, 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 (like white or light gray). This severely impacts readability for users with visual impairments, including those with low vision, color blindness, or cataracts. Text rendered in this color on a light background may be virtually illegible. To ensure accessibility, it's crucial to use Ultramarine sparingly and pair it with very light colors. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) is recommended according to WCAG guidelines. Tools like contrast checkers can help verify compliance. Consider providing alternative color schemes for users who need them.
