The color #2E5DBF, also known as Cerulean Blue, presents some accessibility challenges. Its relatively low luminance can create insufficient contrast against lighter backgrounds, making text or interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. To ensure accessibility, it's best practice to use this color with darker backgrounds to meet contrast requirements.
