I'm developing a simple idea plug-in. In this plug-in, toolwindow will host my form. I want to know how to set colors for the form. For example, for a text, I want it to be displayed in blue under the light theme and yellow under the darula theme. How should I do it in a standardized way. In addition, I want to add some beautiful components on the idea in the form. Can you give me some help or guidance?
