Blurry Search Icon (Widget) & Search Text Color

Hello,

The search icon on the search widget and search page is blurry and slightly larger than the search text box. It doesn’t look to good, so I was wondering if CSS code or something could fix it.

Also, is there a way to change the search text color (“Type keywords and press enter” section) without changing the top bar text color? I want all of the text in my top bar to be white, but doing so makes the search text color invisible.

Thank you
