General Information about Ultramarine

The hex color #0D0B90, commonly known as Ultramarine, is a deep and rich shade of blue that sits between blue and violet on the color spectrum.

In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, it consists of 91% cyan, 92% magenta, 0% yellow, and 44% black. Ultramarine has a sense of depth and sophistication, often associated with royalty and intellect. Due to its high blue component, this color evokes feelings of calmness and tranquility, similar to the deep sea or night sky.

The hex color #0D0B90, also known as Ultramarine, presents some accessibility challenges, primarily due to its dark hue. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Conversely, as a text color, it requires a very light background. Using it with mid-tone colors can result in insufficient contrast, making it difficult for users, especially those with visual impairments, to discern the content. Designers should carefully evaluate color combinations using contrast checkers to adhere to accessibility best practices. Moreover, avoid relying solely on color to convey information; incorporate text labels or other visual cues to ensure inclusivity for color-blind users.
