The color #2250B4, also known as Cerulean Blue, presents some accessibility challenges. Its relatively low lightness value of 0.25 means that text rendered in this color may lack sufficient contrast against a white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a color contrast checker, one can verify if the contrast ratio between #2250B4 and the intended background color meets these requirements. If not, consider using a lighter shade of blue or a darker background to improve readability for users, especially those with visual impairments. Additionally, avoid using this color as the sole indicator of important information, as users with color vision deficiencies may not be able to distinguish it from other colors.
