The color #284F8B, also known as Chambray, presents some accessibility challenges, especially when used as a background or text color. Its relatively low lightness value (around 25%) means that it requires careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background to be considered accessible. When using Chambray for text, it is crucial to pair it with a light color such as white or a very pale yellow to ensure readability for users with visual impairments. Similarly, if Chambray is used as a background, text placed on top should be a light color to meet accessibility standards. Tools such as contrast checkers can be used to verify the contrast ratio between Chambray and other colors. Furthermore, avoid using Chambray for essential UI elements if sufficient contrast cannot be achieved, as this can hinder usability for all users.
