The hex color #2348C4, a shade of cerulean blue, presents some accessibility considerations for web developers. Its relatively low luminance value means that it may not provide sufficient contrast when used as text against a white or very light background. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to be able to read and interact with content effectively. When using this color for text, it is essential to pair it with a very light or white background to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. For decorative elements, a contrast ratio of 3:1 is required. Tools and online contrast checkers can help measure the contrast ratio between this color and background colors. When used for interactive elements, it's important to ensure that the color provides sufficient visual cues to indicate the element's state (e.g., hover, focus, or active).
