The hex color #1B3CCB, also known as Persian Blue, presents some accessibility challenges, particularly when used as a text color. Its relatively low luminance value of approximately 0.12 means that it requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. When using #1B3CCB for text, it's crucial to pair it with a light background color to meet these contrast requirements. Using a darker background could make the text difficult or impossible for users with visual impairments to read. For interactive elements like buttons or links, providing clear visual cues beyond color alone is essential, such as underlines, borders, or icons. Also, make sure you do not use this color in case you need to convey an important message as colorblind users will likely not distinguish this color properly.
