The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as it was originally derived from the mineral lapis lazuli, imported from distant lands. Historically, it was a highly prized and expensive pigment used by Renaissance painters for its vibrant and enduring color. Today, synthetic ultramarine provides a more accessible alternative while retaining the color's distinctive qualities. It is often associated with royalty, depth, and clarity.

The color #001094, also known as Ultramarine, presents significant accessibility challenges due to its very dark hue. When used as a foreground color against a white background, it provides extremely low contrast, failing WCAG (Web Content Accessibility Guidelines) standards for readability. This can make text or interactive elements nearly impossible for users with visual impairments to discern. To improve accessibility, it's crucial to pair this color with much lighter shades, such as light grays, yellows, or even near-white tones, to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using this color for crucial interface elements without careful consideration of its impact on users with low vision or color blindness. Providing alternative high-contrast themes is also a good practice. Testing with accessibility tools is essential to validate compliance.
