I was looking for an "Everything is Red" Theme. It's difficult to find these types of Themes, that are also fully functional. When I say fully functional, I mean that all elements of a Firefox Window are of the specified color and are fully distinguishable from one another. The Active Tab is way more visible than other Themes I've tested, but it could be just a bit more. The one thing that doesn't quite work is when you're typing in the Address Bar, when the Drop-Down Menu of Suggestions appears, you can't see what you've selected because the Blue Text disappears in the Blue Background. Other than this, I consider this Theme to be one of the best of this Type.

The red is not lurid, nor does it distract from the white tab font. Its dark gradation and subtle polygons are an elegant touch. The address bar is consistent with the tabs with about the same level of contrast and similar background color. It is pleasing rather than somewhat sinister like red on black.

I like that it's distinctly red but not too bright and gives a good contrast to the white text.
