The hex color #15187A, also known as Deep Koamaru, presents some accessibility challenges, especially when used as a background color for text. Due to its dark nature, it requires light-colored text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. When using #15187A, it's crucial to test the contrast ratio with tools like WebAIM's Contrast Checker to verify compliance. Pairing this color with white (#FFFFFF) or a very light shade of yellow or green can improve accessibility. Avoid using it with dark text colors, as this will result in a low contrast ratio and make it difficult for users, especially those with visual impairments, to read the content. Consider providing alternative color schemes for users who need them.
