The color #190395, a deep ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using this color for small text on a dark or moderately colored background would make it illegible for many users, including those with visual impairments. For interactive elements like buttons or links, sufficient contrast is crucial to ensure users can easily identify and interact with them. Web developers should rigorously test color combinations using contrast checkers to ensure compliance with accessibility standards. Also consider providing alternative high-contrast themes for users who require them. It is also not recommendable to use this color as the main color for interactive visualizations like graphs or charts.
