Color in a typical contemporary screen
 

The screen shows a Macintosh user interface with two open Microsoft Word windows that contain text that has been edited and is marked by red font and yellow in the background
 

The screen looks relatively colorful, but this is due to text being edited (red font indicates changed text, and yellow background signals marked text). The general appearance of the application shown here is very much monochrome, as is the case for most other commercial applications today.
