The hex color #15314E, also known as Nile Blue, presents certain accessibility challenges, particularly concerning text legibility. Due to its relatively low luminance, using this color for text on a white or light background may result in insufficient contrast, making it difficult for users, especially those with visual impairments, to read comfortably.

It's crucial to evaluate the contrast ratio of #15314E against the intended background color using online tools to ensure compliance. To enhance accessibility, consider using #15314E sparingly for decorative elements or larger graphical components, and always pair it with lighter text colors like white or very light grays to improve readability. For optimal accessibility, explore alternative, lighter shades of blue or consider adding a background behind the text to improve contrast.
