The color #223A54, also known as Cello, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, or vice versa, it may not meet the WCAG (Web Content Accessibility Guidelines) standards for contrast ratio, potentially making it difficult for users with visual impairments to read. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, when using #223A54 for text, it's crucial to pair it with a background color that provides sufficient contrast. Lighter shades of yellow or orange, or even a very light gray, could be good choices. For background usage, consider using a lighter text color. Tools are available online to check color contrast ratios and ensure compliance with accessibility standards. Remember that providing sufficient contrast is not only beneficial for people with disabilities but also enhances the overall readability and user experience for everyone.
