The color #0F3F8B, also known as Congress Blue, presents some accessibility challenges, especially when used as text on a white background. Its low luminance and contrast ratio make it difficult for users with visual impairments to read comfortably. 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. Congress Blue often falls short of these recommendations, potentially excluding users with low vision or color blindness. When using this color for text, consider pairing it with a very light color, like white or a pale yellow, to improve contrast. Alternatively, use Congress Blue for larger graphical elements where readability is less critical. Tools are available online to calculate contrast ratios and ensure compliance with accessibility standards, helping developers create inclusive designs that cater to a wider range of users.
