Reverse video
（重定向自Inverse video）
Reverse video (or invert video or inverse video or 'reverse screen') is a computer display technique whereby the background and text color values are inverted. On older computers, displays were usually designed to display text on a black background by default. For emphasis, the color scheme was swapped to bright background with dark text. Nowadays the two tend to be switched, since most computers today default to white as a background color. The opposite of reverse video is known as true video.
