The color name "Ultramarine" comes from the Latin "ultramarinus", literally "beyond the sea", as the pigment was originally imported from mines in Afghanistan by sea to Europe.

The color #100BA9, a deep shade of ultramarine, presents significant accessibility challenges, especially in text-based contexts. Its low luminance contrast against common background colors like white necessitates careful consideration. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This dark blue hue often falls short of these requirements when paired with lighter backgrounds, making text difficult to read for individuals with visual impairments. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light color like white, off-white, or a very pale yellow to provide adequate contrast. When using this color, always test the contrast ratio using online tools or accessibility checkers to ensure compliance with accessibility standards and a positive user experience for all users.
