The color #0B3F85, also known as Congress Blue, presents some accessibility challenges, particularly when used as text on a white background. Its relatively low luminance contrast ratio may make it difficult for individuals with visual impairments to read comfortably. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Congress Blue, careful consideration should be given to font size and weight to improve readability. Combining it with a very light color like white or yellow or a dark color such as black can help to improve its accessibility. To ensure optimal accessibility, it is advised to use Congress Blue with a lighter background color or to increase the text size and weight. Testing with accessibility evaluation tools is also recommended to identify and address any potential issues.
