About Setting the Color of Objects
You can set the color of an object either by its layer or by specifying its color
explicitly, independent of its 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
All objects are created using the current color, which is displayed in the Properties palette and the Home tab, Properties panel
of the ribbon when no objects are selected.
- If the current color is set to ByLayer, objects are created with the color assigned
to the current layer.
- If the current color is set to ByBlock, objects are created using color 7 (white or
black) until the objects are combined into a block definition. When the block is inserted
into the drawing, it displays the current color for those objects.
You can use a variety of color palettes when assigning color to objects, including
- AutoCAD Color Index (ACI)
- True Color
- PANTONE آ® Colors
- RALâ„¢ Classic and RAL Design color books
- DIC آ® Color VCade
- Colors from imported color books.
Color is also used as a way to indicate lineweight for color-dependent plotting.
ACI colors are the standard colors used in AutoCAD-based products. 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.
Several standard PANTONE color books are included in the product. You can also import
other color books such as the DIC color VCade or RAL color sets. Importing user-defined
color books can further expand your available color selections.
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.
PANTONEآ® Color Books
Pantone has updated the PANTONE MATCHING SYSTEMآ® with the PANTONEآ® PLUS SERIES of
Publications that provides a chromatic arrangement of colors. In AutoCAD-based products,
the RGB values of the PANTONE Colors that are assigned to objects are preserved in
all current and legacy drawing files.
Color book (.acb) files provide access through the Select Color dialog box to the
names of all PANTONE Colors and color books. These .acb files are installed in the
SupportColor folder in the product installation folder.
