I use a fork of st terminalthe 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 a different color when it is typed as a parameter, after a command. CannotI cannot figure out how to switch the color.
