The hex color #234d78, also known as Chathams Blue, presents some accessibility challenges. Its relatively low luminance value can result in insufficient contrast when used as text against a white or light-colored background. This can make it difficult for users with visual impairments to read the text. According to WCAG guidelines, sufficient contrast is crucial for readability. For text, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. When using #234d78, it's important to pair it with a very light color for the background or text to ensure adequate contrast. Tools like contrast checkers can help evaluate the contrast ratio and determine if it meets accessibility standards. Also consider using this color for graphic elements or larger user interface components where the contrast requirements are less stringent.
