The color #135085, also known as Chathams Blue, presents some accessibility challenges, especially when used as text on a white background. Its low lightness value results in a low contrast ratio, potentially making it difficult for users with visual impairments to read the text. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Chathams Blue may not meet these requirements, necessitating careful consideration of font size and weight. When using this color, ensure to pair it with a very light color like white or a light shade of yellow to enhance readability. Tools are available to test the contrast ratio to ensure it meets accessibility standards. Also, avoid using it for crucial interactive elements, such as buttons, without sufficient visual cues.
