General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1A148A, is a deep, saturated blue hue reminiscent of the precious pigment derived from lapis lazuli. This color, often associated with royalty, wisdom, and serenity, sits firmly within the blue color family, exhibiting a certain depth and richness that sets it apart from lighter or more airy blues. Its historical significance stems from its use in Renaissance paintings, where it was prized for its luminosity and permanence. In modern contexts, Ultramarine continues to be a popular choice for conveying a sense of sophistication and elegance, often finding its place in branding, web design, and even interior decor where a touch of classic refinement is desired.

The Ultramarine color, #1A148A, presents some accessibility challenges, especially when used for text or interactive elements. Its dark hue results in low contrast against similarly dark backgrounds, making it difficult for users with visual impairments to perceive content effectively. To ensure accessibility, it is crucial to pair Ultramarine with light or vibrant colors that provide a high contrast ratio, ideally exceeding the WCAG (Web Content Accessibility Guidelines) recommended ratios of 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using Ultramarine for crucial visual cues without providing alternative indicators, such as labels or symbols. When using this color, it's essential to test its contrast against various background colors using accessibility evaluation tools to ensure readability and usability for all users, including those with color vision deficiencies or low vision.
