General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #020999, is a deep, rich blue hue known for its historical significance and modern applications. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it was originally made from ground lapis lazuli, a rare and expensive gemstone imported from Afghanistan. This made ultramarine a highly prized pigment in Renaissance painting, often reserved for depicting the robes of the Virgin Mary. Today, synthetic ultramarine is widely available, retaining the same vibrant color at a fraction of the cost. In the RGB color model, #020999 consists of 0.8% red, 3.53% green, and 60% blue. It exudes a sense of sophistication and depth, making it a popular choice in various design fields.

The color #020999, a deep ultramarine, presents significant accessibility challenges, especially when used as text on a white background. Its low luminance value results in very poor contrast, failing WCAG standards for normal text sizes. To improve accessibility, consider using it for larger text elements like headings, or pair it with much lighter colors such as white (#FFFFFF), light yellows (#FFFFE0), or pale blues (#ADD8E6) to ensure sufficient contrast ratio (at least 4.5:1 for normal text and 3:1 for large text). When using this color for interactive elements like buttons, make sure the focus state is clearly indicated with a contrasting outline or background change. Avoid using it for crucial information, such as error messages, without additional visual cues to compensate for the low contrast. Testing with accessibility tools is highly recommended to ensure compliance and a positive user experience for people with visual impairments.
