Colors are filters that can help you to pick out only the tasks with the specific color. First of all you need to think of the colors legend. For instance, our company uses the following color legend:
To assign a color to a project or a task you should click the one you need (so that it is highlighted) choose the color in the â€œAdditional infoâ€ panel and press “Save” button.
If I need to see all my tasks for Marketing I choose yellow square in the left bottom corner, my name and all projects.
After that all tasks that suit this parameters are shown “In filter”.
