General Information about Ultramarine

Ultramarine, represented by the hex code #0A0791, is a deep blue color that resembles the pigment derived from the gemstone lapis lazuli. Historically, ultramarine pigment was highly valued and expensive, making it a color associated with royalty, importance and luxury. In modern color theory, ultramarine is considered a cool color that evokes feelings of calmness, serenity, and authority. In additive color systems (like those used in screens), ultramarine is created by blending red, green, and blue light, while in subtractive color systems (like those used in printing), it is created by mixing cyan, magenta, and yellow pigments. The hexadecimal representation provides a standardized way to represent this color across various digital platforms and applications.

The hex color #0A0791, also known as Ultramarine, presents some accessibility challenges, especially regarding 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. Using a color contrast checker is highly recommended to verify compliance. Avoid pairing this color with other dark shades, as it can result in illegible content for users with visual impairments. Consider providing alternative color schemes for users who may need them.
