The color #183B5A, also known as Cello, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it's crucial to select foreground text colors that provide sufficient contrast to ensure readability for 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. Therefore, pairing Cello with light colors such as #FFFFFF (white) or other light shades will be necessary to meet these standards. Tools like contrast checkers can help verify compliance. Additionally, avoid using Cello as the sole indicator for interactive elements; supplement with text labels or other visual cues to aid users who may not perceive color differences well.
