The color #223D66, also known as Cello, presents some accessibility considerations for web developers. Due to its relatively dark hue, it's crucial to ensure sufficient contrast when used as either a text or background color. Following WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular). When using Cello for text, pair it with a light color to ensure readability for users with visual impairments. Conversely, if Cello serves as a background, opt for light-colored text or UI elements. It's always advisable to test color combinations with accessibility tools to verify compliance with accessibility standards and cater to a wider audience, including individuals with low vision or color blindness. Avoid using color as the sole indicator of information. Providing redundant cues, such as text labels or icons, enhances the usability for all users.
