Its dark hue results in a relatively high contrast ratio against white text, which is generally beneficial for readability. However, it's crucial to ensure sufficient contrast when pairing it with other colors, particularly lighter shades. Tools like contrast checkers can help verify compliance with WCAG guidelines, aiming for a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. When used as a background color, be mindful of the text color chosen; light text colors such as white or light yellow work best. Avoid pairing it with very dark or similarly saturated colors to maintain legibility for users with visual impairments. Moreover, always consider providing alternative styling options for users who may need to customize color schemes to suit their individual needs.
