It has a relatively low saturation and luminance, contributing to its muted and somewhat mysterious appearance. In color psychology, dark blues are often associated with intelligence, authority, and sophistication. This particular shade of ultramarine can be seen as a classic and timeless color choice, suitable for a variety of applications from digital design to traditional art forms. The hex code is a compact way to represent this precise color value across different platforms and mediums.

The color #150791, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance value means that text rendered in this color requires careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, particularly for users with visual impairments. For normal text (size smaller than 18pt), a contrast ratio of at least 4.5:1 is recommended, while for large text (at least 18pt or 14pt bold), a ratio of 3:1 is necessary. Using #150791 for text on a white background would likely fail these contrast tests. To improve accessibility, designers should pair this color with very light shades or consider using it sparingly for non-textual elements. It is recommended to test the contrast ratio using online tools to ensure compliance with accessibility standards and provide an inclusive user experience. Additionally, providing alternative color schemes or themes can further enhance accessibility for users with specific visual preferences or needs.
