Can I Change The Find Box Colour?

[ASUNDER]

It's very dark.

I found it:

Preferences: Colors and fonts / Windows colors > Window Contents > Workspace
And/Or ... > Windows Contents > Background
That's better. A touch of blue, is nice.

It's the Background color. Workspace isn't used for much (used to mean the desktop background color, but I think the actual desktop tends to use something else now).
