How to change iMac "Messages" progress bar color

[jman995x]

Sometimes when I'm texting someone using the Messages app on my iMac, it'll take up to 15 seconds or so for the message to send.
The messages I send are green in color, but so is the "progress bar" at the top of the window, so the progress bar blends into the message at the top of the window and gets lost.
Is there any way to change this color to something that will contrast with the green message it's fading into?

If this doesn't make any sense, I can include a screenshot next time Messages is lagging and I encounter this problem.

Not that I know of but coming at it the other way you can use Bubble Painter to change the green bubble colour.

Unless the progress bar follows that colour...

Perfect!
Thanks for the suggestion.
A much better solution than I was hoping for.

Thanks.
