The hex color #274EBF, also known as Cerulean Blue, presents some accessibility considerations for web developers. Its relatively low luminance means that using it as a background color for text can create contrast issues, especially for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. When using #274EBF, it's crucial to pair it with a light color for text to ensure sufficient contrast. White (#FFFFFF) or very light shades of gray would be good choices. Tools like contrast checkers can help verify compliance with accessibility standards. Also, consider providing alternative styling options for users who may need further customization to perceive content clearly. Ensure that interactive elements using this color have clear focus indicators.
