Thunderbird header pane color change

Thunderbird Customization

I am running Windows 11 with Thunderbird V144 and the Windows Classic theme. I find the background colors of the Message List Pane and the Message Pane almost the same as background of the Header pane. I would like to change the background color of the Header Pane so that it stands out more. I looked on the internet and found some solutions to most other Header Pane features but not the background color. Most of those solutions were additions to the userChrome.css file that appear not to work on V144.

I would appreciate some help with this.

Add this to userChrome.css (see pictures): 

#threadPaneHeaderBar{background-color: lightblue !important;}

#messageHeader{background-color: lightgreen !important;}
