The color #2563B1, also known as Fun Blue, provides moderate contrast against white text.

When using Fun Blue as a background, ensure that interactive elements like buttons and links have sufficient contrast. Adding a dark border around interactive elements can also improve visibility for users with low vision. For optimal accessibility, avoid pairing Fun Blue with colors of similar luminance, as this can make it difficult for users to distinguish between elements. Thoroughly test your designs with accessibility tools to guarantee usability for all users, including those with visual impairments.
