The hex color #1E3B5A, also known as Cello, presents some accessibility challenges, especially when used as a background color for text. Its relatively low luminance of approximately 8% requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to ensure readability for users with moderate visual impairments. When using #1E3B5A as a background, it is crucial to select a light text color to meet these contrast requirements. White or very light shades of yellow or orange could be suitable choices. Tools like the WebAIM Contrast Checker can be used to verify the contrast ratio. Failure to meet these standards can exclude users with low vision or color blindness from accessing the content. Also, avoid using color alone to convey important information, as this is inaccessible to color-blind users. Supplement color cues with text labels or icons.
