This variable is used to choose a background intensity. Use one of these values:
| 0 |
The runtime uses the default intensity, which is based on your hardware and operating environment. Under Windows, the default
background intensity is high-intensity. The default value is "0".
|
| 1 |
The runtime uses low-intensity. |
| 2 |
The runtime uses high-intensity. |
There are two important exceptions:
- The runtime always assigns low-intensity to the background if the background color is black. Using high-intensity would cause
the background to be dark gray, which tends to make the screen look muddy.
- Many devices do not support a background intensity independent from the foreground intensity (most terminals, for example).
When that is the case, the runtime declares the background intensity to be low-intensity.
