The hex color #2155C5, also known as Cerulean Blue, offers moderate accessibility. When used as text against a white background, the contrast ratio is approximately 2.9:1, which is below the WCAG recommended minimum of 4.5:1 for normal text and 3:1 for large text. Therefore, it's advisable to use it for larger text sizes or decorative elements rather than body text to ensure readability for users with visual impairments. Pairing it with lighter shades of yellow or off-white can improve contrast. When used as a background color, consider using white or very light text colors to enhance readability. Color blindness simulators indicate that individuals with protanopia, deuteranopia, or tritanopia will perceive the color with slight variations in hue and saturation, but readability issues are unlikely to be severe if adequate contrast is maintained with the foreground elements.
