The color #1F384C, a dark, desaturated blue, presents some accessibility challenges, especially when used for text. Its low luminance value requires careful consideration of contrast ratios against background colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to ensure readability for users with moderate visual impairments. When using #1F384C for text, it's crucial to pair it with a very light background color to meet these contrast requirements. White or very light shades of yellow, green, or blue are good options. Avoid using #1F384C with mid-tone or dark backgrounds, as this will likely result in insufficient contrast, making the text difficult or impossible to read for many users. Also consider providing alternative styling options (e.g. high contrast mode) to the user.
