Colors from imported color books.
ACI Colors
ACI colors are the standard colors used in AutoCAD. 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.
Color Books
This program includes several standard Pantone color books. You can also
import other color books such as the DIC color guide or RAL color sets.
Importing user-defined color books can further expand your available color
selections.
NOTE Pantone has provided new color definitions for Architectural & Interiors
Cotton and Architectural & Interiors Paper color books. If you used these color
books in releases prior to AutoCAD 2006, you may notice subtle changes in the
colors.
You install color books on your system by using the Files tab in the Options
dialog box. Once a color book is loaded, you can select colors from the color
book and apply them to objects in your drawings.
All objects are created using the current color, which is displayed in the Color
control on the Properties toolbar. You can also set the current color with the
Color control or the Select Color dialog box.
If the current color is set to BYLAYER, objects are created with the color
assigned to the current layer. If you do not want the current color to be the
color assigned to the current layer, you can specify a different color.
If the current color is set to BYBLOCK, objects are created using color 7 (white
or black) until the objects are grouped into a block. When the block is inserted
into the drawing, it acquires the current color setting.
