The color #0047AB, also known as Cobalt, presents some accessibility challenges, especially when used as text on a white background. Its contrast ratio is not high enough to meet WCAG (Web Content Accessibility Guidelines) AA standards for normal text sizes. Therefore, using this color for text requires careful consideration. To improve accessibility, pair it with very light backgrounds (like whites or very pale yellows) or use it for larger text elements where the contrast requirements are less stringent. Alternatively, consider using it for decorative elements rather than essential information. When using it for interactive elements like buttons, ensure that hover and focus states provide sufficient contrast. For individuals with low vision or color blindness, the low contrast may make it difficult to distinguish text or elements using this color. Tools like contrast checkers can help assess and improve accessibility.
