General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #021199, is a deep, intense shade of blue. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally made from lapis lazuli imported from faraway lands. Lapis lazuli is a semi-precious stone prized for its rich blue hue. Historically, ultramarine pigment was highly valued and expensive, making it a favorite among artists for depicting religious figures and royalty. Nowadays, synthetic ultramarine is readily available, making it more accessible for various applications. The color evokes feelings of depth, calmness, and sophistication. Its deep saturation lends itself well to both digital and physical applications, making it a versatile color choice for designers and artists.

The color #021199, a deep ultramarine, presents significant accessibility challenges for web content. Its extremely low luminance value necessitates careful consideration of contrast ratios. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards 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) to ensure compliance. This color should be avoided for essential text or interactive elements if sufficient contrast cannot be achieved. For users with low vision or color blindness, the lack of contrast can render content illegible. Providing alternative color schemes or a user-adjustable contrast setting is crucial for inclusivity. It's imperative to test color combinations using accessibility tools to verify compliance and ensure a positive user experience for everyone.
