Video Display and Display Adapter 9-27
The menu options perform the following functions.
Object
Selecting this option allows you to change the color of
any AutoCAD screen object, such as the graphics area
background color, the menu area text color, or the
border line color.
Select an object to change by moving the highlight box
around with the left and right cursor control keys and
pressing <Enter> after highlighting the object you want.
A one-line description of the object type displays at the
top of the screen as you move the box around.
Select the object, and another highlight box appears
around the color boxes near the bottom of the screen.
These are the physical colors that the Gateway 2000
VGA card supports. Use the left and right cursor keys
(as well as the up and down keys in the 256 color mode)
to select which physical color to use for your object and
then press <Enter>. The screen quickly redraws with the
new color selection for that object. Now you are back at
the start of the object selection process in case you want
to change the color of another object.
When you change the background color to a new color
in COLOR16, all drawing colors identical to that new
color swap with the previous background color.
For example, if the current background color is white
and you change it to blue, all the boxes in the drawing
color area (middle of the screen in 16 color mode) that
used to be the same shade of blue are now white. In the
16 color mode, drawing color 0 always reflects the
background color.
In COLOR256, changing the background color only
causes physical color 0 to assume the same color as the
color you select. This does not affect any other colors,
unless you chose color 0 for another object, in which case
it has the same color as the new background.
