This is a map of topics the I cover in my project. The topics are segmented in different stages, and I would like to have your advice on how to color the segments. I check the color wheel to find a suitable color template, but I don't see one really fit with the yellow sky and blue water. In the end I set them while altogether. I satisfy with this, but since I want to learn more about color theory, if you can recommend a good template that would be nice.
For some background, The Sphere and Theory of perspective are two of my projects. The latter is the underlying theoretical framework for the former, while the former is the application of the latter. Most of my audience only need to know the former, so I think the iceberg analogy is suitable. Yes I'm aware that 7/8ths of an iceberg is below the water line, but I guess as long as the analogy serves the purpose it doesn't matter much.
