The hex color #2A61BC, also known as Cerulean Blue, presents moderate accessibility considerations. Its contrast ratio against white is approximately 3.47:1, which is below the WCAG recommended ratio of 4.5:1 for normal text and 3:1 for large text. This means that using #2A61BC for text on a white background might be difficult for users with visual impairments to read comfortably. To improve accessibility, consider using a lighter background color to increase the contrast ratio, or using a darker shade of blue for the text. When using this color for UI elements, make sure the contrast ratio meets accessibility guidelines to ensure a good user experience for everyone. Consider implementing colorblindness emulators during the design phase to check how users with different types of colorblindness perceive the color combination.
