The color #2A51BC, also known as Cerulean Blue, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it's crucial to pair it with text colors that offer sufficient contrast to ensure readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, pairing #2A51BC with a light color like white (#FFFFFF) or a very light gray is advisable.

Proper attention to these details will greatly improve the inclusivity of designs incorporating this vibrant blue.
