The hex color #2d51b9, also known as Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white is approximately 3.7:1, which falls short of the WCAG's recommended 4.5:1 for normal text. Therefore, using #2d51b9 for text on a white background may be difficult for users with low vision. To improve accessibility, consider using a lighter shade of blue or a darker background. When pairing this color with text, ensure that the font size is large enough (18pt or 14pt bold) to meet WCAG AA standards. For optimal accessibility, aim for a contrast ratio of 7:1, especially for critical elements and calls to action. Thoroughly test color combinations with accessibility tools to verify compliance and provide the best user experience.
