General Information about Ultramarine

Ultramarine, represented by the hex code #09118E, is a deep blue pigment known for its rich and intense color. It derives its name from the Latin 'ultramarinus', meaning 'beyond the sea', as the original pigment was imported from regions beyond the sea, primarily from Afghanistan. Historically, it was made by grinding lapis lazuli into a powder. Due to its labor-intensive production process and the rarity of lapis lazuli, ultramarine was a highly prized and expensive pigment, often reserved for the most important figures and elements in paintings, such as the robes of the Virgin Mary. Nowadays, synthetic ultramarine is widely available, offering the same vibrant color at a fraction of the cost.

The accessibility of #09118E (Ultramarine) for text depends heavily on the background color it's paired with. Due to its dark nature and low luminance, it requires very light text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, and 3:1 for large text (14pt bold or 18pt regular). Tools like WebAIM's Contrast Checker can help verify compliance with WCAG guidelines. When using Ultramarine for interactive elements, ensure that hover, focus, and active states have distinct visual changes to aid users with visual impairments and those who rely on keyboard navigation. It's generally not advisable to use Ultramarine for large blocks of text, but it may work as a background color behind white text.
