#001299

General Information about Ultramarine

Ultramarine, represented by the hex code #001299, is a deep, rich blue color that evokes feelings of depth, stability, and sophistication. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly prized pigments of the Renaissance. Its name, derived from the Latin "ultramarinus," meaning "beyond the sea," reflects its origin from stones imported into Europe from faraway lands. The color is associated with royalty, spirituality, and artistic expression. In modern color theory, ultramarine is considered a cool color, capable of creating a sense of calm and serenity. It's commonly used in design to convey trust, reliability, and intellectual depth.

The color #001299, a deep shade of ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 1% means that it provides very little contrast against a black background, making it nearly invisible. When used as text or interactive elements, it becomes problematic for users with low vision or color blindness. To ensure accessibility, it is imperative to pair this color with a light background, such as white or a very pale yellow. The contrast ratio should ideally be above 4.5:1, as recommended by WCAG guidelines for normal text, and above 3:1 for large text. Providing alternative text descriptions for images or elements using this color is also vital. Additionally, avoid using this color as the sole indicator of interactive elements, and always provide alternative visual cues like underlines or icons.
