Take the 2-minute tour ×  I was looking for this for a long time
but I couldn't find anything. Please tell me how to change the
color of Unity's menu bar if it is possible.  Not the left panel
(launcher), I mean the panel on the top of the Unity desktop.

The top panel (for which the proper term is "menu bar") in Unity
gets its theme from the currently set GTK+3 theme. Notice that
depending on whether you select Ambiance or Radiance the color
of the menu bar changes to match your window titlebars. So, one
option is to simply find, install, and select a different GTK+3
theme. However, this also changes the theme for the rest of your
desktop.  Method 2  An alternate solution you may try requires a
little bit of work, but could potentially give you a lot of
control over how the end result looks. The following method
describes how to change the appearance of the menu bar by making
it transparent and modifying your wallpaper to get the look you
want:
