The color #0F4D8B, also known as Congress Blue, presents some accessibility challenges, especially when used as text on a white background. With a relatively low contrast ratio, it may be difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #0F4D8B for body text on a white background might not meet these standards. To improve accessibility, consider using a lighter shade of blue or a darker background. Alternatively, you can increase the font size and weight to enhance readability. Tools like contrast checkers can help assess and adjust color combinations for optimal accessibility. Ensure that important visual information is not solely conveyed through color.
