The color #18159F, a deep ultramarine, presents significant accessibility challenges, particularly in text applications. Its low luminance necessitates high contrast ratios against background colors to ensure readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #18159F for text, light colors such as white (#FFFFFF) or very light yellows or greens are advisable for backgrounds.

In graphical user interfaces, consider the size and importance of elements using this color. Larger elements or crucial interactive components might tolerate slightly lower contrast, but sufficient contrast is crucial for usability. Always test color combinations with accessibility evaluation tools to ensure compliance with accessibility standards and accommodate users with diverse visual abilities.
