The hex color #0643AE, also known as Cobalt, presents some accessibility challenges, especially for text-based content. Its dark hue results in a low contrast ratio against white backgrounds, making it difficult for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Cobalt falls short of these recommendations when paired with white. To improve accessibility, consider using a lighter tint of Cobalt or pairing it with a much lighter color such as white, light yellow, or light gray to achieve sufficient contrast. Alternatively, using Cobalt as a background color with white or very light text can enhance readability. Tools like contrast checkers can help verify if the contrast ratio meets accessibility standards.
