How To Permanently Change PowerShell's Configuration?

My Power Shell got screwed up - the input colours got changed to yellow and I couldn't find a way to change them back... And on my old monitor I can't read the yellow.

Lots of stuff on the web about it. Recurring problem. Solutions here and there that don't work.

Finally found something that works but I have to input it every time i start up Power Shell.

Here it is:

Code:

 Set-PSReadLineOption -Colors @{
"Error" = [ConsoleColor]::DarkRed
"String" = "$([char]0x1b)[38;5;100m"
"Command" = "#8181f7" }

Does the job. Input is blue, I'd rather have black but blue will do.

But how do I put that into Power Shell's configuration so's it stays there?

Hi....

no, they didn't, that was the problem. the given solutions just didn't work. I haven't revisited them since I found the solution I've shown. It could be they'd work now.... they change such things as time goes on, don't they....

that's what all the forum posts i found were about.... folks who found the given solutions didn't work....

i'll check them out again some time... are they the only permanent config amendment routes ?

p.s. it was one of those that got me into it in the first place... I researched changing colours and did as instructed and then found I couldn't get back.... as I remember the only one that wouldn't change back was the input text one...

why'd I go in the first place? just wanted to change from that awful nowadays trendy black screen to a white one...
