Its name, meaning 'beyond the sea,' reflects its historical importation into Europe from mines in Asia. In color theory, Ultramarine is associated with royalty, wisdom, and spirituality. It is often used to evoke feelings of calmness and serenity. The color sits between blue and violet on the color wheel and has a hex code of #2401B3, an RGB value of (36, 1, 179) and a CMYK value of (80, 72, 0, 30). In digital design, Ultramarine can add a sense of sophistication and depth, but its darkness requires careful consideration of contrast and accessibility.

The color #2401B3, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast against lighter backgrounds, making text and interface elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability. To improve accessibility, consider using #2401B3 sparingly, primarily for decorative elements. When using it for text or interactive components, pair it with very light colors like #FFFFFF or #F0F0F0 to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Also, provide alternative visual cues, such as icons or labels, to convey information. Avoid using #2401B3 for critical information where readability is paramount. Testing the color combination with accessibility evaluation tools is highly recommended to validate contrast ratios and identify potential issues.
