#1D0F89

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1d0f89, is a deep, saturated blue hue reminiscent of the precious pigment derived from lapis lazuli. It falls within the blue-violet spectrum and is often associated with feelings of depth, tranquility, and sophistication. In color theory, ultramarine is considered a cool color, making it effective for creating a sense of calm or formality. Its relative darkness makes it less reflective than lighter blues, contributing to a more grounded and serious aesthetic. This color finds application across various fields, from graphic design and web development to fashion and fine art. Historically, it was one of the most expensive and sought-after blue pigments.

The hex color #1d0f89, also known as Ultramarine, presents some accessibility challenges, particularly in text applications. Its dark hue results in a low contrast ratio against standard white backgrounds, potentially making it difficult for users with visual impairments to read. To enhance accessibility, consider pairing it with lighter colors like white, light gray, or a muted yellow. When using it as a background, ensure that the foreground text is sufficiently bright to meet WCAG (Web Content Accessibility Guidelines) contrast requirements. Large text benefits from higher contrast than smaller text. Also, avoid using this color to convey critical information without additional cues, such as icons or labels, to ensure inclusivity for colorblind users. Thoughtful color selection significantly improves the usability of your designs for everyone.
