The hex color #215BC5, also known as Cerulean Blue, presents specific accessibility considerations for web design. When using this color for text, ensure a sufficient contrast ratio against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (18pt or 14pt bold). Given its relatively dark hue, #215BC5 works best with lighter backgrounds. Testing the color combination with accessibility tools is crucial to confirm compliance. Consider providing alternative color schemes for users with visual impairments. Using this color as a primary background element may cause readability problems if text contrast is not addressed. It is advised to use a color contrast checker and consider that individuals perceive colors differently, and what appears accessible to one person might not be for another.
