#1D05AE

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1D05AE, is a deep, vivid shade of blue. It derives its name from the Latin 'ultramarinus', meaning 'beyond the sea', as the original pigment was imported from mines in Afghanistan by sea to Europe. Historically, Ultramarine was made by grinding lapis lazuli into a powder. This made it one of the most expensive and prized pigments, often reserved for important commissions, such as depictions of the Virgin Mary's robes. Today, synthetic alternatives offer the same vibrant color at a fraction of the cost. In the RGB color model, #1D05AE consists of 11.4% red, 2% green, and 68.2% blue. Its symbolic associations often include royalty, wisdom, and spirituality.

Ultramarine, represented by the hex code #1D05AE, presents specific accessibility considerations for web design. Its dark hue results in a low luminance value, which necessitates careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, using light colors such as white (#FFFFFF) or light shades of yellow or green as foreground text on an Ultramarine background is crucial for readability. Conversely, avoid using dark text colors like black or dark grays, as they would fail to provide adequate contrast, making the content difficult to read for users, especially those with visual impairments. Proper contrast is essential for users with low vision or color blindness.
