This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
Antiope had similar capabilities to the UK system for displaying alphanumeric text and chunky "mosaic" character-based block graphics. A difference however was that while in the UK standard control codes automatically also occupied one character position on screen, Antiope allowed for "non spacing" control codes. This gave Antiope slightly more ...
2×3 cell graphic block characters on a 40×25 character page. 2 colors per block, chosen from 8 primary colors (1 bit each of red, green, and blue). The first row is reserved for a page header and attributes are set with control codes which each occupy one character position giving a maximum resolution of 78×72. Apple II (1977)
Teletext has 40×25 characters per page of which the first row is reserved for a page header. Every character cell has a background color and a text color.

Text terminal windows present a character-based, command-driven text user interfaces within the overall graphical interface. MS-DOS and Unix consoles are examples of these types of windows. Terminal windows often conform to the hotkey and display conventions of CRT-based terminals that predate GUIs, such as the VT-100.
All characters on the screen with this bit set will periodically blink, meaning their foreground color will be changed to their background color so the character becomes invisible. All characters blink in unison. By setting a hardware register, the blink feature can be disabled, restoring access to high-intensity background colors. All blinking ...
