General Information about Ultramarine (#0D009B)

The color #0D009B, commonly known as Ultramarine, is a deep and intense shade of blue. It belongs to the blue color family and exhibits a strong presence due to its high saturation and relatively low brightness. In the RGB color model, it is composed of 5.1% red, 0% green, and 61.2% blue. In the CMYK color model, it consists of 92% cyan, 100% magenta, 0% yellow, and 39% black. Ultramarine is often associated with feelings of depth, stability, and sophistication. Its historical significance stems from its use in fine art, where it was originally derived from the precious mineral lapis lazuli, making it a highly valued and expensive pigment.

The hex color #0D009B, also known as Ultramarine, presents significant accessibility challenges due to its dark nature. When used as a foreground color, it requires very light background colors to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using #0D009B on a white background fails to meet these standards, making text difficult to read. To improve accessibility, consider pairing it with colors like #FFFFFF (white) or #FAF9F6 (light beige), and always test the color combination with accessibility tools to verify compliance. Also avoid using this color for crucial interactive elements without clear visual cues.
