The hex color #2750BF, a shade of Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white is relatively low, potentially causing readability issues for users with visual impairments. When used for text, it's crucial to pair it with a light background to ensure sufficient contrast, meeting WCAG guidelines for text and non-text contrast. Consider using a color contrast checker to verify compliance. For interactive elements like buttons or links, ensure sufficient size and clear visual cues in addition to color contrast, as color alone should not be the sole indicator of functionality.

To improve accessibility, explore slightly lighter or darker shades that offer better contrast while maintaining the intended aesthetic. This color works best for decorative elements and accents, where contrast is less critical.
