The color #283B56, also known as Cello, presents specific accessibility considerations for web design. With its relatively low lightness value, 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). When using Cello for text, pairing it with lighter colors like white (#FFFFFF) or light gray (#D3D3D3) is essential to meet these standards.
