Its high chroma and dark value make it visually striking, and it can evoke feelings of calmness and serenity. The RGB values for Ultramarine are R:26, G:13, B:142, indicating a strong dominance of blue with minimal red and green components. When printing, the CMYK values are C:82, M:91, Y:0, K:44. Its use in digital interfaces should be considered carefully due to accessibility concerns related to contrast.

The color #1A0D8E (Ultramarine) presents some accessibility challenges due to its dark nature. When used as a background color, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. It's crucial to test color combinations using accessibility tools to verify compliance. Using this color for small text or intricate graphical details against a dark background can lead to poor visibility and a negative user experience. Designers should consider users with visual impairments who may struggle to distinguish elements with low contrast. Providing alternative high-contrast themes or allowing users to adjust color settings can greatly improve accessibility for everyone. Proper use of ARIA attributes and semantic HTML can also aid assistive technologies in interpreting content effectively.
