You can undercoat with any color really. It's less about color theory and more about how pigments have different sizes, making some colors naturally more transparent. If you want a solid yellow base coat your just going to have to apply more thin layers to achieve it. Also don't thin yellow paint with water, use a paint medium instead. As for why they often use purple as an undercoat, it's because they aren't going for a solid yellow base coat. Using purple is a way of pre shading the model, purple is yellows complementary color, leaving some purple in the recesses complements the yellow as its "Shadow". Here's a basic color theory chart for those who want a reference.I've seen people use weird things like purple as a base and get the most beautiful yellows ever. Probably some color theory shit a lot of us are too tarded or lazy to get into.
