The hex color #1F49D1, also known as Cerulean Blue, presents some accessibility challenges, especially in text contexts. Its relatively low luminance value means that using it as text on a white background may result in insufficient contrast, making it difficult for users with visual impairments to read comfortably. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Cerulean Blue often falls short of these requirements when paired with light backgrounds. Therefore, it's crucial to use contrast checking tools to ensure compliance. To improve accessibility, consider using Cerulean Blue with darker backgrounds or pairing it with lighter text colors such as white or very light grays to achieve the necessary contrast ratio. Additionally, avoid using it for essential interactive elements without sufficient contrast, as this can hinder usability for all users, particularly those with disabilities.
