You can change the color of an object by
reassigning it to another layer, by changing the color of the layer
the object is on, or by specifying a color for the object
You have three
choices for changing the color of an object:
Reassign the object to another layer with a different color. If
an object's color is set to BYLAYER, and you reassign the object to
a different layer, it acquires its color from the new layer.
Change the color assigned to the layer that the object is on.
If an object's color is set to BYLAYER, it acquires the color of
its layer. When you change the color assigned to a layer, all
objects on that layer assigned the BYLAYER color are updated
Specify a color for an object to override the layer's color.
You can specify the color of each object explicitly. If you want to
override the layer-determined color of an object with a different
one, change an existing object's color from BYLAYER to a specific
color, such as red.
If you want to
set a specific color for all subsequently created objects, change
the current color setting on the Properties toolbar from BYLAYER to
a specific color.
