Why does powershell call the color sapphire, darkmagenta?

Just a weird thing I’ve noticed in powershell. When you run get-psreadlineoption, it says the background is darkmagenta, but it looks more like dark blue or sapphire.

Comes from .Net: https://msdn.microsoft.com/en-us/library/system.windows.media.colors(v=vs.110).aspx
DarkMagenta Gets the system-defined color that has an ARGB value of #FF8B008B.

But the appearance is actually #012456 or rgb(1,36,86) or sapphire in the windows console or ise. I guess other settings override it.

You could use Color Tool: https://github.com/Microsoft/console/releases/tag/1708.14008
I set it to OneHalflights, reasonably OK now.

It doesn’t seem to run.

You run it from powershell prompt, not as a standalone. It will show command-line options you can use.
