How to get the taskbar color?

Question

I want to make my app the same color as the taskbar.

1)
In Windows 10 it is possible to use the accent color for the taskbar. How do I determine if the taskbar is in the accent color?

2)
Under Windows 10, if the taskbar is not in the accent color, how can I determine the color of the taskbar? Are there only 2 colors possible here (one for light design and one for dark design)?

3)
In Windows 11, I have not found any way in the Windows settings to display the taskbar color in the accent color or to derive it from the accent color. Do I have only 2 colors (for dark and light design) to choose from in Windows 11? How do I determine the color of the taskbar?

Answer 1

On Windows 10, if it uses Accent color, ColorPrevalence is set to 1

(HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize)

A way to get its color is to read it physically, like for example :
