The color #183858, also known as Cello, presents some accessibility challenges, especially when used as a background color for text. Due to its dark hue, it requires careful consideration of color contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial. For small text, a contrast ratio of at least 4.5:1 is recommended, while large text requires a ratio of 3:1. When using #183858 for text, it's essential to pair it with a light color to meet these standards. White (#FFFFFF) or light shades of gray or yellow would be good choices to enhance readability. Tools like WebAIM's Contrast Checker can help verify compliance. If the contrast is insufficient, consider using a lighter shade of Cello or choosing an alternative, lighter color altogether. Non-text elements should have a contrast of 3:1 against adjacent colors.
