What is the proper use of grey fonts?
Designers will often use grey fonts, rather then black, as a design element on a Web page. While this can help add contrast to content and improve the look and feel, it can also make the content hard to read on the monitor or screen. This can also become more difficult for the user if the content is on a grey or off-white background.
It is best to use solid black fonts on a white background so it is easy for the user to read. The ability to read content is more important then the design elements of the content.
Good design should be appropriate for the target market and compliment the Website’s usability.
