General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #080497, is a deep blue pigment originally derived from the precious mineral lapis lazuli. This explains its historical significance and association with royalty and high status. Chemically, it is a complex sodium aluminum silicate with sulfur, giving it its distinctive blue hue. In the RGB color model, it consists of 3.14% red, 1.57% green, and 59.22% blue. Due to its rich and intense color, Ultramarine has been widely used throughout history in various forms of art, including paintings and illuminated manuscripts. Today, synthetic versions of Ultramarine are readily available, making it a more accessible and affordable pigment for artists and designers.

The hex color #080497, also known as Ultramarine, presents significant accessibility challenges, primarily due to its very dark nature. When used as a background color, it necessitates extremely light text to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine falls short with most standard text colors like black or even dark grays. Therefore, using this color requires careful consideration of foreground text colors. White or very light shades of yellow or other high-contrast colors are essential to meet accessibility requirements. Tools like contrast checkers can help designers verify compliance. Moreover, relying solely on color to convey information should be avoided; supplementary cues like text labels or icons are necessary for users with color vision deficiencies.
