I am totally new to automation and trying to learn RobotFramework. I am trying to write the scripts following some video guide. Usually robot scripts autocomplete in PyCharm IDE with desired color. I found the whole script along with 4 sections(Settings, Variables, Test cases and Keywords) are in green. Not sure how to change that thing.
