I use a fork of st terminal. When I type anything after a dollar sign, I cannot see the text because it blends in with the background. I use dir_colors to change colors of different file types. But I don't know the definition of that particular type.

For example, suppose I type $TERM. Until $TER, the color is similar to the background color but after typing $TERM, it becomes red. It is in different color when it is typed as a parameter, after command. Cannot figure out how to switch the color.
