General Information about Ultramarine

Ultramarine, represented by the hex code #0000A0, is a deep blue color that evokes feelings of tranquility, depth, and sophistication. It is a variant of blue, specifically a dark shade that resembles the pigment derived from lapis lazuli. In color theory, Ultramarine sits opposite yellow-orange on the color wheel, making yellow-orange its complementary color. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported into Europe from Asia. This color is often associated with royalty, intelligence, and stability. In the digital realm, Ultramarine can be used to create a sense of trust and reliability, making it a popular choice for corporate branding and user interface design.

The hex color #0000A0, also known as Ultramarine, presents significant accessibility challenges, especially in text-based applications. Its low luminance value results in a very low contrast ratio against standard white backgrounds, making it difficult for users with visual impairments to read text displayed in this color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine falls far short of these recommendations. To enhance accessibility, consider using lighter shades of blue or pairing it with a light, contrasting background color like white, yellow, or a pale grey. Tools such as contrast checkers can help determine if a color combination meets accessibility standards, ensuring content is perceivable and usable for all users, including those with disabilities.
