The hex color #223F63, also known as Cello, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value means that text rendered in this color against a white background may not meet WCAG (Web Content Accessibility Guidelines) AA standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #223F63 for text, it's crucial to pair it with a light background color to ensure readability. Alternatively, consider using it for decorative elements or backgrounds where text is not essential. Tools like contrast checkers can help determine if the combination meets accessibility requirements. Also, avoid using this color to indicate status or convey critical information alone, without additional visual cues, as those who are color blind may not be able to distinguish it.
