Why does ncurses support only eight colors?

If you've looked into the color palette available in curses, you may wonder why curses supports only eight colors. The curses.h include file defines these color macros:

COLOR_BLACK COLOR_RED COLOR_GREEN COLOR_YELLOW COLOR_BLUE COLOR_MAGENTA COLOR_CYAN COLOR_WHITE

But why only eight colors, and why these particular colors? At least with the Linux console, if you're running on a PC, the color range's origins are with the PC hardware.

A Brief History of Color

Linux started as a PC operating system, so the first Linux console was a PC running in text mode. And to understand the color palette on the PC console, you need to go all the way back to the old CGA days. In text mode, the PC terminal had a color palette of 16 colors, enumerated 0 (black) to 15 (white). Backgrounds were limited to the first eight colors:

  • 0. Black
  • 1. Blue
  • 2. Green
  • 3. Cyan
  • 4. Red
  • 5. Magenta
  • 6. Brown
  • 7. White ("Light Gray")
  • 8. Bright Black ("Gray")
  • 9. Bright Blue
  • 10. Bright Green
  • 11. Bright Cyan
  • 12. Bright Red
  • 13. Bright Magenta
  • 14. Yellow
  • 15. Bright White

These colors go back to CGA, IBM's Color/Graphics Adapter from the earlier PC-compatible computers. This was a step up from the plain monochrome displays; as the name implies, monochrome could display only black or white. CGA could display a limited range of colors.

CGA supports mixing red (R), green (G) and blue (B) colors. In its simplest form, RGB is either "on" or "off". In this case, you can mix the RGB colors in 2x2x2=8 ways. Table 1 shows the binary and decimal representations of RGB.

Table 1. Binary and Decimal Representations of RGB 000 (0) Black 001 (1) Blue 010 (2) Green 011 (3) Cyan 100 (4) Red 101 (5) Magenta 110 (6) Yellow 111 (7) White

To double the number of colors, CGA added an extra bit called the "intensifier" bit. With the intensifier bit set, the red, green and blue colors would be set to their maximum values. Without the intensifier bit, each RGB value would be set to a "midrange" intensity. Let's represent that intensifier bit as an extra 1 or 0 in the binary color representation, as iRGB (Table 2).

Arctic Posts Second Warmest Year On Record In 2018, NOAA Says

Slashdot - Thu, 12/13/2018 - 04:00
According to a new report released on Tuesday by the U.S. National Oceanographic and Atmospheric Administration, the Arctic had its second-hottest year on record in 2018. "Arctic air temperatures for the past five years have exceeded all previous records since 1900," according to the annual NOAA study, the 2018 Arctic Report Card, which said the year was second only to 2016 in overall warmth in the region. Reuters reports: The study said the Arctic warming continues at about double the rate of the rest of the planet, and that the trend appears to be altering the shape and strength of the jet stream air current that influences weather in the Northern Hemisphere. "Growing atmospheric warmth in the Arctic results in a sluggish and unusually wavy jet-stream that coincided with abnormal weather events," it said, noting that the changing patterns have often brought unusually frigid temperatures to areas south of the Arctic Circle. Some examples are "a swarm of severe winter storms in the eastern United States in 2018, and the extreme cold outbreak in Europe in March 2018 known as 'the Beast from the East.'"
