DuckDuckGo's dark theme is almost perfect. Only problem is a flash of white, and depending on how long it takes to load the page, can blind you when you're on a long searching stint.

This theme simply colors those parts that flash white, the rest of the DuckDuckGo theme really is good.

I've kept the coloring in the grey tones to match the already grey-toned DuckDuckGo theme(s).
