General Information about Ultramarine

The color #0B0A91, commonly known as Ultramarine, is a deep shade of blue situated in the blue-violet segment of the color spectrum. It evokes feelings of calmness, depth, and sophistication. Historically, Ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a highly prized pigment among Renaissance painters. Today, it is synthetically produced, making it more accessible. This color is often associated with royalty, wisdom, and spirituality. In color psychology, blue is generally linked to trust, stability, and intelligence. Ultramarine, being a darker shade, can also convey authority and formality. It is frequently used in corporate branding and design where these qualities are desired. Its hex code, #0B0A91, represents its unique combination of red, green, and blue light components, which when mixed, create this distinct shade of blue.

The hex color #0B0A91, also known as Ultramarine, presents certain accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet Level AA compliance. For Level AAA, the contrast ratios are even stricter. This dark shade of blue might not meet these ratios with many common text colors. Therefore, designers and developers must carefully evaluate color pairings. Tools and online contrast checkers are helpful in assessing compliance. Furthermore, consider providing alternative color schemes or themes to accommodate users with visual impairments or preferences. Offering high-contrast mode options or allowing users to customize colors can significantly improve accessibility.
