The color #283A5B, also known as Cello, presents some accessibility considerations for web development. With a relatively low luminance, it's crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet AA standards. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. When using Cello, pairing it with lighter colors like whites, creams, or light yellows will significantly improve readability and accessibility. Tools like contrast checkers can help verify compliance. Avoid using Cello for small text or elements that require fine detail, as this could cause eye strain for users, especially those with visual impairments. Ensuring proper color contrast is essential for creating inclusive and user-friendly web experiences.
