It is also often associated with the night sky and the ocean, evoking feelings of calmness and serenity.
The color #15009B, a deep ultramarine, presents significant accessibility challenges. Its low luminance value of approximately 2% means that it offers very poor contrast against white text. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. This color would fail these criteria, making it difficult for users with visual impairments to read text rendered in this color against a light background. Similarly, using white or light-colored text on a #15009B background may strain the eyes of some users. To improve accessibility, consider using a lighter shade of blue or a contrasting color like yellow or orange for text and interactive elements. Ensuring sufficient contrast is crucial for readability and usability for all users, including those with low vision or color blindness. Proper contrast enhances the user experience and ensures that content is perceivable and understandable.
