General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #12098C, is a deep and intense shade of blue. Historically, ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a pigment highly valued by artists throughout history. The name 'ultramarine' literally means 'beyond the sea,' referring to the fact that the pigment had to be imported into Europe from mines in Asia. Due to its historical significance and striking hue, ultramarine is often associated with royalty, spirituality, and artistic expression. Modern ultramarine is now synthesized, making it more accessible for various applications, yet it retains its connection to its rich past and inherent qualities of depth and intensity.

The color #12098C, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value (around 2%) means that it offers very poor contrast against white text or backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability. This dark blue shade falls far short of these standards. To improve accessibility, consider using it sparingly or pairing it with very light colors like white (#FFFFFF) or pale yellow (#FFFFE0) to achieve an acceptable contrast ratio. Tools like contrast checkers can help you measure the contrast ratio and ensure compliance with accessibility standards. Avoid using this color for critical information or interactive elements unless sufficient contrast is provided.
