The hex color #1B4FCB, a shade of Cerulean Blue, presents some accessibility challenges, particularly in text-based applications. Its relatively low lightness value (compared to pure white) means that using it as a background color for light text can result in insufficient contrast, making the text difficult to read for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #1B4FCB, it's crucial to pair it with very light colors like white (#FFFFFF) or light yellow (#FFFFE0) to ensure adequate contrast. Utilizing contrast checking tools is highly recommended. This color might be better suited for decorative elements rather than critical text elements where readability is paramount. Dark text on this background can be a viable solution, but careful testing is crucial. Consider alternatives or modifications (adjusting lightness/saturation) to improve accessibility if contrast requirements aren't met.
