Hi Gypsycomp,

There are thunderbird themes around - you could try those.

The subject bar if just a plain text field, so even if you do colour it, it won't show up that way in the recipiant's inbox.

Does that help?

I want to color the subject-date-size bar above the incoming emails in my inbox, not the recipients inbox.

There is a way to change colour of 'Header columns' bar.

make hidden files and folders visible:

• http://kb.mozillazine.org/Show_hidden_files_and_folders

• Help > Troubleshooting Information
• click on 'Show Folders'

A window opens showing your profile folder.

• Close Thunderbird now - this is important.

• Create a folder and call it chrome. - note the spelling.
• Save it in the profile folder name in the same place as the 'Mail' folder.

see first image below.

• Open Notepad - Start > Programs > Accessories > Notepad
• Copy all between the lines below and paste into Notepad.
• Save the file as userChrome.css - note the spelling - in the chrome folder.

then close window - top right X Restart Thunderbird

/*

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); 

/*Code changes colour of column header background*/

treecol, .treecol-image {
-moz-appearance: none !important;
background-color: peachpuff !important;
}

Note; In the code, where it says 'peachpuff', you can use a different colour name or use colour hex code eg: #FFDAB9 see this link:
