General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D0D8E, is a deep blue pigment historically derived from lapis lazuli. The name "ultramarine" literally means "beyond the sea," referring to its origin as a pigment imported from Asia. In color theory, ultramarine is considered a primary color, though in the RGB color model, it's a variation achieved through a combination of red, green, and blue light. This specific shade of ultramarine is characterized by its strong blue saturation and relatively low brightness. Its darkness makes it suitable for creating depth and shadow in visual designs. While visually appealing, its low luminance requires careful consideration for accessibility in digital applications, particularly regarding text contrast.

The color #0D0D8E, also known as Ultramarine, presents significant accessibility challenges, primarily due to its very low luminance. Its contrast ratio against a white background is extremely poor, making it difficult for users with visual impairments to discern text or other elements rendered in this color. In web design, it's crucial to ensure sufficient contrast between foreground and background colors to comply with WCAG guidelines. Using #0D0D8E for text or important UI elements without careful consideration of contrast could exclude a significant portion of users. To improve accessibility, consider using a lighter background or employing a text shadow or outline to enhance readability. Tools such as contrast checkers can help determine if the color combination meets accessibility standards. Avoid using this color for essential information without proper contrast adjustments.
