Its relatively low lightness value means that it requires careful consideration of contrast ratios to ensure readability for users with visual impairments.

Failure to do so may result in text that is difficult or impossible for some users to read. In graphical user interfaces, it is important to consider the size and weight of text rendered in #174F81, as well as the background color against which it is displayed. Sufficient spacing between lines of text can also improve readability.
