General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #06019A, is a deep and intense shade of blue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and prized pigments. The name 'ultramarine' literally means 'beyond the sea,' as the pigment was imported into Europe from mines in Asia. This color is known for its exceptional depth, brilliance, and lightfastness. In the RGB color model, #06019A is composed of 2.4% red, 0.4% green, and 60.4% blue. In the CMYK color model, it consists of 96% cyan, 99% magenta, 0% yellow, and 39.6% black. Ultramarine is often associated with royalty, intellect, and spirituality, due to its historical connection to wealth and its use in religious art. Modern ultramarine is typically synthesized, making it more accessible and affordable while retaining its vibrant qualities.

The color #06019A, a deep Ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance value of approximately 1, makes it difficult to read text against a background of this color. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast between text and background is crucial for readability, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine, due to its darkness, would likely require very light text (e.g., white or very pale yellow) to meet these standards. Using this color as a background for large areas of text should be avoided. Careful consideration should be given to the font size, weight, and surrounding context to ensure content is accessible to all users, including those with color vision deficiencies or low vision. Employing tools to check contrast ratios is highly recommended during the design process.
