Work with Colors
Color helps to group objects visually. You can assign colors to objects by layer
or individually.
Set the Current Color
You can use color to help you identify objects visually. You can assign the
color of an object either by layer or by specifying its color explicitly,
independent of layer.
Assigning colors by layer makes it easy to identify each layer within your
drawing. Assigning colors explicitly provides additional distinctions between
objects on the same layer. Color is also used as a way to indicate lineweight
for color-dependent plotting.
You can use a variety of color palettes when assigning color to objects,
including

ACI Colors
ACI colors are the standard colors used in AutoCAD LT. Each color is identified
by an ACI number, an integer from 1 through 255. Standard color names are
available only for colors 1 through 7. The colors are assigned as follows: 1 Red,
2 Yellow, 3 Green, 4 Cyan, 5 Blue, 6 Magenta, 7 White/Black.
True Colors
True colors use 24-bit color definitions to display over 16 million colors. When
specifying true colors, you can use either an RGB or HSL color model. With
the RGB color model, you can specify the red, green, and blue components
of the color; with the HSL color model, you can specify the hue, saturation,
and luminance aspects of the color.
