The color #18405E, also known as Cello, presents some accessibility challenges, primarily due to its darkness. When used as a background color, sufficient contrast is crucial for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Given its low lightness value, #18405E requires very light text colors (e.g., white or very pale shades) to meet these contrast requirements. Without adequate contrast, text can become difficult or impossible to read, leading to a poor user experience. In situations where #18405E is used for interactive elements like buttons or links, it is essential to ensure that the color difference between the normal state, hover state, and active state is significant enough to be easily distinguishable. Using color alone to convey information is not accessible, so additional cues like text labels or icons should be provided.
