The color #183A5A, also known as Cello, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it is crucial to ensure that any text or interactive elements layered on top have sufficient contrast to be easily readable by individuals 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 and UI components. Therefore, pairing Cello with light-colored text, such as white or very light shades of yellow or gray, is advisable to meet these accessibility standards. Tools like online contrast checkers can be invaluable in verifying compliance. Furthermore, avoid using this color for essential visual cues without providing alternative cues, like text labels or icons, to ensure inclusivity for all users.
