Search options background color is the same as color

[ricobonfim]

At the top right corner of the frontend there's a search functionality where you can write something and filter by a list of options (Address, Block Height or Transaction).

The select itself is set with a background color transparent and color white, and the options inherit it from the select. The problem is that options can't have a background color transparent (at least I couldn't do it), so we end up with both background-color and color as white. The user can still select and see the content when it hovers since it changes de background color to blue.

I've tried a couple of different approaches for background-color transparent and none worked, so I think we have 2 options here:

1. Set options background-color to something close to the position they're positioned (ie: #2c1f2e)
2. Set options color to black (since it's the default anyway)

Not really sure how 1 would look like on mobile though
