The color #1F1F79, also known as Deep Koamaru, presents some accessibility challenges, especially when used for text. Its low luminance value of 0.02 means that it offers poor contrast against light backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to meet AA compliance. Given the darkness of this color, using it for text on a white or very light background would likely fail these criteria. To improve accessibility, pair #1F1F79 with very light colors such as #FFFFFF (white) or consider using it for decorative elements rather than critical text. Ensuring sufficient contrast is crucial for users with visual impairments to perceive content effectively. When using #1F1F79 for interactive elements, ensure proper focus indicators are visible.
