Happy to answer any questions, but reply to the thread with a new post instead of editing an older post, or I might not see the new question.
It might be useful for you to explore leveraging the properties of groups and components in relation to materials. In short, a material applied to a surface on the inside of a component will override any color applied to the outside. So if you make a fresh component with the default material (or lack of material) and apply the paint bucket to the component, you will color the entire component in one click. Because all the surfaces inside the component do not have a material on them within the component they will continue to accept any color you put on the outside of the component.
If you open the component and paint a particular surface with a material, it will override anything applied to the outside of the container. This is particularly useful in situations where you want some part of the component to retain a particular color while being able to change the rest of the surfaces in one click. For example if you made a car you would paint the “glass” material on the window surfaces inside the component and leave the rest default, then from the outside you could change the cars color to whatever you wanted in one click without disturbing the glass.
