Answer 1

Create your own converter ( https://www.wpf-tutorial.com/en/39/%D1%81%D0%B2%D1... ) and bind to the background property of your top element in the cell template, and specify the converter , and in the converter you return the corresponding color value. If it's completely unclear, I'll write the code for you.

Answer 2

You can't put a lot of code here, the rest is in the comments. This example doesn't rely heavily on Mvvm, so the window code is a collection, not a model view. The MvvmLight library is used.
