General Information About Ultramarine

Ultramarine, represented by the hexadecimal color code #150FA4, is a deep, vivid blue hue. It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally sourced from the semi-precious stone lapis lazuli, imported to Europe from distant lands, primarily Afghanistan. In the realm of color theory, Ultramarine sits between blue and violet on the color wheel, exhibiting a rich and intense character. It is composed of approximately 8.24% red, 5.88% green, and 64.31% blue. Historically, Ultramarine pigment was highly prized by artists due to its brilliance and permanence, often reserved for depicting important figures and religious subjects. Synthetic Ultramarine, chemically identical to the natural pigment, was developed in the 19th century, making the color more accessible and affordable. Today, Ultramarine remains a popular choice in various applications, from art and design to fashion and cosmetics, valued for its depth, vibrancy, and historical significance.

The color #150FA4, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments or color vision deficiencies. Its low luminance and high saturation mean that it offers insufficient contrast against lighter backgrounds, making text difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Ultramarine often falls short of these benchmarks when paired with common background colors like white or light gray. Therefore, careful consideration must be given to its usage. To enhance accessibility, it is advisable to use Ultramarine sparingly, particularly for text elements. Pair it with very light or highly contrasting background colors to ensure readability. Providing alternative color schemes or allowing users to customize the color settings can further improve the accessibility of designs incorporating this vibrant hue. Additionally, avoid relying solely on color to convey important information; use text labels or other visual cues to ensure that content is accessible to all users.
