In The Dark 3.5.2

The GUI craze of today is round, glassy, and bubbly. They take up resources, distract the eye, and in many cases, inhibit productivity and understanding. In The Dark 3.5.2 is a step in a different direction for user interfaces. It's designed to be minimalistic, using a total of six colors: black, white, and four shades of gray, which it employs in a standard and logical manner in order to easily see icons and objects, determine the state of those objects, and what they do.
In The Dark 3.5.2 uses high-clarity icons to make even the smallest buttons easy to understand, keeping the interface from hindering your work. Items you can click are easily identified by a noticeable alteration of color. Menus stay flat against the background until you need them, and the selected item makes itself clearly known without being displeasing to the eyes. The entire interface uses a very dark-oriented tone to keep your eyes from being strained by light, and white text sticks out plainly without being overpowering or hard to read. Interfaces which must have black text, such as many properties windows in Microsoft Windows XP, instead get a dark gray background, just light enough to read the black text without being an eyesore or sticking out from the rest of the theme.
