The color #283A55, also known as Cello, presents some accessibility challenges, particularly regarding color contrast. When used as text on a white background, or vice versa, it may not meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. This can make it difficult for users with visual impairments to read the text. Therefore, it's crucial to pair Cello with lighter hues, such as shades of white, cream, or light yellows, to ensure sufficient contrast. Similarly, if Cello is used as a background, text should be in a light color to ensure readability. Tools for checking color contrast are widely available online and should be a standard part of the design process. It's always recommended to test color combinations with real users, including those with visual impairments, to ensure optimal accessibility. Consider using this color for decorative elements where legibility is less critical.
