General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F0FA4, is a deep and rich shade of blue. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally imported from overseas, particularly from sources of lapis lazuli. Chemically, it's a complex sodium aluminosilicate with sulfur, responsible for its distinctive hue. In the RGB color model, #0F0FA4 consists of 5.9% red, 5.9% green, and 64.3% blue. This composition contributes to its strong blue presence and relatively dark appearance. Ultramarine has a long and storied history, prized in art for its vibrant and lasting color. Its synthetic version, French ultramarine, made it more accessible and affordable, revolutionizing its use in various applications.

The color #0F0FA4, a deep shade of ultramarine, presents some accessibility challenges, particularly in text applications. Its low luminance value (relative darkness) means that it requires careful consideration of contrast ratios. When used as a text color, it is crucial to pair it with a very light background to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Using online contrast checkers can help verify compliance. In user interface design, avoid using this color for essential interactive elements without sufficient contrast. For users with visual impairments, especially those with low vision or color blindness, poor contrast can render text or interactive elements invisible or difficult to distinguish. Designers should also consider providing alternative color schemes to accommodate different user preferences and needs.
