In 1.6 xmls it's all the states of Address, Breadcrumb, & Search > Search > SearchBox > Basic > Normal > Active > Background
in 1.4 xmls it's Address, Breadcrumb, & Search > Search > SearchBox > Basic > Normal > Active > Background > 1 & 2
Change the images.
I think that hover color is Explorer & Shell > Explorer > ListView > ListItem > Selected
If I go into Address, Breadcrumb, & Search > Search > SearchBox > Basic > Normal > Active > 1 for 1.4,
it brings me to the image want to use for the SearchBox, but in my preview I'm showing how once I want to commence a search, the searchbox for the back of the text turns black, making the text the user would type in, essentially unreadable.
