In its simplest form, creating a custom uniform is much like coloring between the lines. In GIMP, the lines we set as the boundaries for color are called Paths. If you open the Paths panel, you’ll see various paths with uniform part names. The Paths panel is opened by clicking on the Paths tab in the Layers window.
These paths act as the guides (boundaries) for colorizing the uniform. For example, if we click on the the Upper Torso Front Only Arms path, you’ll see those pieces of the uniform are selected. If you go back to the Layers panel and turn off the visibility for the template uniform, the selected path will be much more obvious.
If we choose the Path to Selection button, the line changes to a dashed line, indicating it’s been selected. When a path is selected, you can only color inside of that selected path.
