The color #303F4D, also known as Oxford Blue, presents some accessibility challenges, especially when used for text. Its relatively dark nature requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #303F4D as a background, it's crucial to pair it with a light foreground color to meet these standards. Insufficient contrast can make text difficult or impossible to read for individuals with low vision or color blindness. Tools like contrast checkers can help verify compliance. Moreover, avoid relying solely on color to convey important information, as colorblind users may not be able to distinguish #303F4D from similar dark hues.
