The hex color #223D59, also known as Cello, presents some accessibility challenges, particularly in text applications. Its low luminance value of approximately 5.5 cd/m² means that it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against a background. When using #223D59 for text, a very light background color is necessary to meet these contrast requirements. Conversely, if #223D59 is used as a background, a light-colored text should be chosen to ensure accessibility. Tools like contrast checkers can help verify compliance with accessibility standards. It's crucial to test color combinations with real users, especially those with visual impairments, to validate that the design is accessible and usable.
