iCE colors
An ANSI-art technique that turns off text blinking to free all 16 colours for use as backgrounds too.
In the standard text-mode palette the background can only be one of eight colours; the top attribute bit instead controls whether the character blinks. iCE colors switches blinking off and reinterprets that bit as "bright background", making all 16 colours available for both foreground and background. The result is twice as many colour combinations for the ANSI artist.
The name comes from the group iCE (Insane Creators Enterprise), which popularised the trick on the 1990s BBS scene. The catch: the image only looks right in viewers and terminals that honour the mode — on a blinking terminal the whole piece flickers. A SAUCE record can flag that a file assumes iCE colors.
