The color #1F3248, also known as Nile Blue, presents some accessibility challenges, especially when used as text on a white or light background. Its low luminance contrast can make it difficult for users with visual impairments to read comfortably. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color falls short of those recommendations when paired with light colors. To improve accessibility, consider using a lighter shade of this color for backgrounds with dark text or pairing it with a much lighter color as a text color. For example, using white text on a #1F3248 background improves the contrast ratio. It's also crucial to test color combinations with accessibility evaluation tools to ensure compliance with accessibility standards and provide a better user experience for all users, including those with color blindness or low vision. Providing sufficient contrast helps to ensure content is perceivable.
