The color #2B48BB, also known as Cerulean Blue, presents some accessibility challenges, especially in text-based applications. Due to its relatively low luminance, it may be difficult to read text rendered in this color against a white or light background. A contrast ratio check is strongly recommended to ensure readability, particularly for users with visual impairments. A minimum contrast ratio of 4.5:1 is generally recommended for normal text and 3:1 for large text. If using #2B48BB for text, consider pairing it with a very light color like white or a pale yellow to meet accessibility standards.
