The color #18364D, also known as Nile Blue, presents some accessibility challenges, particularly regarding contrast. When used as text against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) minimum contrast ratio of 4.5:1 for normal text, making it difficult for users with visual impairments to read comfortably. Similarly, when used as a background color, sufficient contrast with foreground elements is essential. To improve accessibility, consider using a lighter shade of the color as the background, or pairing it with brighter text colors such as white (#FFFFFF) or a light yellow. It's also crucial to test the color combination with accessibility tools and involve users with disabilities in the testing process to ensure the design is inclusive and user-friendly. Remember that providing alternative text descriptions for images is also important, even when using decorative colors.
